What does 'Purva' mean in relation to yoga?

In the context of yoga, 'Purva' means 'East.' This term is derived from Sanskrit, where directional words play a significant role in various practices and philosophies. The East is often symbolically connected to new beginnings and enlightenment, making it a relevant direction in yoga and spiritual practices. Many yogic texts and traditions consider facing the east during practices like meditation or asana to align oneself with the rising sun, which can represent the dawn of knowledge and awareness.

The other choices, although valid directions in their own contexts, do not align with the specific meaning of 'Purva' in yoga. For instance, 'West' refers to a different directional aspect, and terms relating to 'Back' or 'Side' refer more to positioning rather than the spiritual significance embodied in the eastern direction.
