It is important to understand the various limbs of Yoga. Unless one understands these limbs of spiritual practice, one shall not be sure or ascertained about the proper spiritual discipline that one should take up. Understanding the nature of mind and its relation to the spirit as well as the world is important. Understanding Jnana and Bhakti in that context becomes vital.
Understanding the Gita through the books is not the same as having an experiential understanding of Gita. it is important to have intrinsic understanding of the Gita. Brahman is that factor which is life in the Within and in the Without. The Gita gives one a perspective and insight into Brahman.
Understanding the Gita, is a primary step towards a life of spirituality. The Gita is perhaps the only document that clearly dilineates the philosophy behind thought, what drives our actions and what one musts do, if one is to relieve himself from the clutches of a bound life. The Gita is an invitation to freedom.
