Anatomy of the Koshas | Online Immersion

Tias Anatomy of the Koshas

Course Description

Since the earliest teachings on yoga, the body-mind is described as having five coverings or casings, called koshas. Like a tree or plant that has progressively more subtle layers from outer bark to pithy interior, the koshas move from outer to inner and from gross to subtle.

In this course we study the anatomical and energetic attributes of each sheath. The first sheath is correlate with food and the outer fascia, the second with breath, the third with thoughts and sensations, and the fourth with the wisdom of the deep fascia. The innermost layer is correlate with the brain and spinal cord and the body of delight.

Through contemplative practice, yoga postures, SATYA (Sensory Awareness for Yoga) and pranayama, we will journey through each stratum, refining and clarifying the subtle body as we go. Layer by layer, we generate greater luminosity and clarity, ultimately yoking to the Source that dwells perpetually in the interior. Each day will include anatomical study, investigation of the wisdom teaching, dynamic and recuperative asana practice, and meditation.
