Amongst most important teachings of Bhagavad Gita laid the fact that we are primarily cosmic consciousness… termed soul atman that manifested human form to work out its karma… remove dross impurities within. As no soul atman could purify self of its own… it always needs a body… a medium to cleanse self of dross impurities within.
Teachings of Bhagavad Gita prove beyond doubt that cosmic life belonged to world of souls’ atmans and not the manifest physical human form. Unless we believed we were a living consciousness… no point reading Bhagavad Gita any further! Our belief in our real self as a soul atman is the primary crux of spiritual life. We failed to realize our true inner self because of presence of ego (termed Aham in Hinduism).
To remove veil of ignorance is ultimate goal of spirituality. Indulgence in teachings contained in Bhagavad Gita removed veil of ignorance step-by-step. It is only by indulgence in jnana yoga (path of absolute wisdom) human beings finally succeeded in removing veil of ignorance forever. Path of jnana yoga can only be traveled by assimilating pearls of jnana (wisdom) contained in Bhagavad Gita. This veil of ignorance has been termed veil of Maya by Adi Shankaracharya.
