Taittiriya Upanishad: The Five Sheaths of the Self

Introduction to the Taittiriya Upanishad

The Taittiriya Upanishad belongs to the Krishna Yajurveda and is one of the major Upanishads that systematically expounds the nature of the self and the ultimate reality. It is divided into three sections or vallis: the Siksha Valli on the science of pronunciation and education, the Brahmananda Valli on the bliss of Brahman, and the Bhrigu Valli on the dialogue between Bhrigu and his father Varuna. This Upanishad is particularly famous for its teaching on the five koshas or sheaths that cover the self, progressing from the gross to the subtle. The Taittiriya Upanishad begins with a beautiful prayer for harmony and peace, invoking the blessings of the divine for the teacher and the student to study together, to grow together, and to protect each other. This prayer reflects the collaborative nature of spiritual learning, where the teacher and student support each other on the path to realization.

The Five Sheaths

The Taittiriya Upanishad presents a unique and systematic analysis of the human personality through the concept of five concentric sheaths that cover the self. The outermost sheath is the annamaya kosha or the food sheath, which is the physical body made of food. Within this is the pranamaya kosha or the vital sheath, composed of the life force or prana. Within that is the manomaya kosha or the mental sheath, consisting of thoughts, emotions, and mental activities. Within that is the vijnanamaya kosha or the wisdom sheath, comprising intellect, discrimination, and knowledge. The innermost is the anandamaya kosha or the bliss sheath, which is the subtlest covering and is experienced as joy and fulfillment. Beyond all these sheaths is the true self, the atman, which is pure consciousness. The Upanishad uses the analogy of a bird to explain these sheaths: the body is like the nest, the vital force like the feathers, the mind like the wings, the intellect like the eyes, and bliss like the egg from which the bird emerges.

The Food Sheath

The annamaya kosha, or the food sheath, is the gross physical body that we can see and touch. It is made of the food we eat and is subject to birth, growth, decay, and death. The Upanishad declares that food is Brahman, emphasizing the sacredness of the material world and the importance of treating the body with respect. From food all beings are born, by food they live, and into food they ultimately merge. The physical body is the foundation of all spiritual practice, and maintaining its health and purity is essential for progress on the path. However, the Upanishad also warns against identifying with the body, as it is only the outermost covering of the self. The true self is beyond the body, untouched by its changes and limitations.

The Vital Sheath

The pranamaya kosha, or the vital sheath, is composed of the five pranas or vital energies that sustain the body and mind. These are prana or the incoming breath, apana or the outgoing breath, vyana or the circulating energy, udana or the ascending energy, and samana or the digestive energy. The vital sheath pervades the physical body and is responsible for all physiological functions. It is more subtle than the food sheath and gives life to the physical body. When the vital force leaves the body, the physical body becomes inert. The Upanishad emphasizes the importance of pranayama or breath control for purifying and strengthening the vital sheath. Through the practice of pranayama, one can gain control over the mind and prepare for deeper meditation.

From food all beings are born. By food they live. Into food they finally merge. Food is the firstborn of creation. Therefore, food is called Brahman. - Taittiriya Upanishad 3.2

The Mental Sheath

The manomaya kosha, or the mental sheath, consists of the mind, thoughts, emotions, and memories. It is the seat of desires, likes, dislikes, and all mental activities. The mental sheath is more subtle than the vital sheath and controls the vital and physical sheaths. The mind is the cause of both bondage and liberation. When the mind is impure and uncontrolled, it leads to suffering and entanglement in the world. When the mind is pure and controlled, it becomes an instrument of liberation. The Upanishad teaches that the mind must be purified through ethical living, study of scriptures, and meditation. A pure mind reflects the light of the self, while an impure mind distorts it. The practice of meditation helps to quiet the mind and turn it inward, allowing the seeker to penetrate deeper into the inner sheaths.

The Wisdom Sheath

The vijnanamaya kosha, or the wisdom sheath, is composed of the intellect, discrimination, and higher knowledge. It is the faculty that distinguishes between the real and the unreal, the eternal and the temporary, the self and the non-self. The wisdom sheath is more subtle than the mental sheath and guides the mind toward truth. When the intellect is illuminated by spiritual knowledge, it leads the seeker to the realization of the self. The Upanishad emphasizes the importance of a qualified teacher and the study of scriptures for awakening the wisdom sheath. Through reflection and contemplation, the intellect turns away from the external world and focuses on the inner reality. The wisdom sheath is the last conceptual covering before the direct realization of the self.

The Bliss Sheath

The anandamaya kosha, or the bliss sheath, is the innermost of the five sheaths and is experienced as joy, fulfillment, and peace. It is the subtlest covering and is closest to the self. The bliss sheath manifests in deep sleep, where there are no desires, no thoughts, and no suffering. It also manifests in moments of great joy, love, and aesthetic appreciation. However, the Upanishad cautions that even the bliss sheath is not the self. It is a covering that reflects the infinite bliss of the self. The true self is beyond all sheaths and is pure consciousness, existence, and bliss. The seeker must penetrate through all five sheaths to realize the self that is beyond them all. The Taittiriya Upanishad concludes by describing the nature of Brahman as truth, knowledge, and infinity. The one who knows Brahman attains the supreme goal and becomes Brahman itself. This teaching inspires seekers to look beyond all coverings and discover their true nature as the infinite, eternal, and blissful self.
