The subtle and often volatile nature of the mind presents a persistent challenge in the pursuit of spiritual understanding. As described by Upasika Kee Nanayon in her teachings, the mind can experience waves of passion or irritation that arise seemingly independent of external stimuli, stemming instead from the inherent disposition of one’s character. These internal states, whether pleasant, painful, or neutral (equanimous), are characterized by their inconstancy and inherent stressfulness, a truth that requires diligent contemplation to prevent the mind from becoming ensnared. This entanglement, particularly with feelings of equanimity, is a subtle trap that obscures clear perception and fosters delusion.
Equanimity, one of the four immeasurables in Buddhist philosophy—alongside loving-kindness, compassion, and sympathetic joy—is often misunderstood as a passive state of indifference. However, its true practice involves a profound engagement with the mind’s internal landscape. Upasika Kee Nanayon emphasizes that while engrossment in pleasure is relatively easy to recognize, the absorption into equanimity can be far more insidious, leading to an oblivious state that hinders clarity. This article will explore the multifaceted uses and critical limitations of equanimity as a spiritual practice, drawing upon the insights of Upasika Kee Nanayon and placing them within the broader context of Buddhist teachings.
Understanding Equanimity: A Deeper Dive
In Buddhist psychology, feelings are categorized into three types: pleasant, painful, and neutral (upekkha, or equanimity). These feelings arise in dependence on sensory contact or mental processes. The challenge lies not in the feelings themselves, but in our reaction to them. Attachment to pleasant feelings, aversion to painful ones, and a subtle complacency or dullness in neutral states can all lead to suffering. Equanimity, when understood correctly, is not the absence of feeling, but rather a balanced and stable mental state that arises from deep insight into the nature of reality.
The four immeasurables, or brahmaviharas, are cultivated as antidotes to negative mental states and as foundations for ethical conduct and spiritual liberation. They are:
- Metta (Loving-Kindness): Wishing well-being and happiness for all beings.
- Karuna (Compassion): The desire to alleviate the suffering of others.
- Mudita (Sympathetic Joy): Rejoicing in the happiness and good fortune of others.
- Upekkha (Equanimity): A balanced, impartial, and steady mind, free from attachment and aversion.
While loving-kindness, compassion, and sympathetic joy are outwardly directed, equanimity is primarily an inward practice, fostering stability and clarity that then informs how we engage with the world.

The Subtle Trap of Oblivious Equanimity
Upasika Kee Nanayon’s teachings highlight a crucial distinction: the difference between genuine, insightful equanimity and an "oblivious equanimity." The latter is a state of mental dullness or complacency that can arise when the mind settles into a placid state without true understanding. This state, while seemingly peaceful, is a form of delusion because it prevents the practitioner from seeing the impermanent and stressful nature of all phenomena.
"Being engrossed in feelings of pleasure is something relatively easy to detect, but being engrossed in feelings of equanimity: That’s hard to notice, because the mind is at equanimity in an oblivious way," Upasika Kee Nanayon explains. This oblivious equanimity acts as a veil, obscuring the fundamental truths of existence: impermanence (anicca), suffering (dukkha), and non-self (anatta).
The implications of mistaking oblivious equanimity for true spiritual progress are significant. Practitioners may believe they have achieved a state of peace, only to find themselves reacting strongly to life’s inevitable challenges. This is because the underlying mental conditioning, the tendencies towards attachment and aversion, remain unaddressed. The mind, in its oblivious state, still harbors "fuel" that can ignite into craving or aversion the moment it encounters sensory experience.
Equanimity as a Foundation for Insight
Despite the potential pitfalls, equanimity, when cultivated correctly, serves as an indispensable tool for spiritual development. Upasika Kee Nanayon emphasizes that when the mind gathers and settles into a state of equanimity, particularly during meditation, this state can be leveraged as a potent basis for developing insight.
"When there’s a feeling of equanimity as the mind gathers and settles down, when it’s not scattered around, use that feeling of equanimity in concentration as the basis for probing in to see inconstancy, stress, and not-self," she advises. This involves observing the equanimous state itself with sharp awareness, not as an end goal, but as a vantage point from which to examine the three characteristics of existence.
This process is particularly potent when the mind reaches deeper states of concentration, such as the fourth level of absorption (jhana). In this state of profound stillness and equanimity, the mind possesses the clarity and stability to penetrate the subtle nature of reality. This is where equanimity transitions from a passive feeling to an active instrument of liberation.

The Role of Jhana and Insight Meditation
The Buddhist path often involves a synergy between concentration practices (like developing jhana) and insight practices (like Vipassanā). Equanimity plays a crucial role in both. Deep concentration states are characterized by profound mental calm and equanimity, providing the stable platform necessary for sustained mindful observation.
The Buddha’s teachings, as transmitted through traditions like the one Upasika Kee Nanayon represents, emphasize the critical importance of not becoming attached to these states of absorption. "Simply make sure that you don’t get attached to the absorption," is a recurring admonition. To do so would be to mistake a temporary mental state for ultimate liberation, thus perpetuating the cycle of delusion.
Instead, the equanimity achieved in jhana becomes the ground for "probing in to contemplate." This means turning the sharp lens of awareness onto the very nature of these absorbed states. Are they truly permanent? Are they free from stress? Do they represent a permanent self? The insights gained here—into inconstancy, stress, and non-self—are what lead to the uprooting of attachments and the dismantling of the egoic structure.
Navigating the Path of Insight
The journey of insight is not linear. Practitioners may experience moments of profound clarity, only to find their minds returning to habitual patterns. The teachings of Upasika Kee Nanayon underscore the need for continuous effort and a nuanced understanding of the process.
"If you get the mind to grow still in equanimity without focusing on gaining insight, it’s simply a temporary state of concentration," she states. This underscores the active, investigative nature of true practice. The equanimity must be a springboard for inquiry, not a comfortable resting place.
The process involves:

- Focusing the mind: Through concentration practices, bringing the mind to a state of stillness and absorption.
- Gaining clear insight: Directing that stable mind to examine the three characteristics of existence (impermanence, stress, non-self) in all phenomena, including the mental states themselves.
- Avoiding attachment to insights: Recognizing that even profound insights are impermanent and subject to change. The goal is not to accumulate insights but to allow them to dissolve the roots of suffering.
- Persistent investigation: Continuously looking for further changes in the mind and observing the stress and non-selfness within those changes. This allows the mind to rise above attachment to any particular level of experience or understanding.
The "Diseases" of the Mind and the Empty Mind
Upasika Kee Nanayon uses the metaphor of "diseases in the mind" to describe the afflictions of greed, aversion, and delusion. The process of examining these diseases is multi-layered. Even when genuine insights arise, it is crucial not to become complacent or boastful. The teachings consistently point back to the core principles: the contemplation of inconstancy without latching on.
This persistent inquiry can lead to even more penetrating insights. The goal is to reach a state where the mind, even amidst mental turmoil and the arising of various mental objects, can perceive them as illusory. By observing their disbanding, the practitioner realizes their insubstantial nature.
"All that remains is the empty mind—the mind maintaining its balance in normalcy—and then focus in on examining that," the teachings suggest. This "empty mind" is not a void but a mind free from defilements, a mind that has seen through the illusion of self and phenomena. It is a mind that has regained its natural balance and clarity.
Purity of Mindfulness and the Foundation of Equanimity
The path culminates in reaching stages such as "purity of mindfulness and equanimity." Here, mindfulness is not just a passive observation but a pure, unadulterated awareness. The equanimity experienced at this stage is not the oblivious kind but is deeply rooted in concentration. It is the very foundation upon which pure mindfulness can operate.
"As for the feeling of equanimity, that’s an affair of concentration. It’s what the mindfulness depends on so that it too can reach equanimity," Upasika Kee Nanayon explains. This interdependent relationship between concentration, equanimity, and mindfulness is key. The centered, equanimous mind, strengthened by concentration, is then able to probe and contemplate with unparalleled clarity. This is the stage where true understanding and liberation become accessible.
The book An Unentangled Knowing: The Teachings of a Thai Buddhist Lay Woman by Upasika Kee Nanayon, translated by Thanissaro Bhikkhu, provides a comprehensive exploration of these profound teachings. Its publication by Insight Meditation Society offers a valuable resource for those seeking to deepen their understanding of Buddhist practice, particularly the nuanced application of equanimity. The continued availability of such texts underscores the enduring relevance of these ancient teachings in addressing the perennial human quest for peace and wisdom. The teachings, originating from a Thai Buddhist lay woman, offer a practical and accessible approach to complex philosophical concepts, emphasizing direct experience and diligent practice. This perspective is crucial for practitioners seeking to integrate spiritual development into their daily lives.
