OM TAT SAT ................ It has been unequivocally determined by the previous acaryas in disciplic succession from the four authorised sampradayas that in order to realize the eternal spiritual truths that apply to all created beings knowledge of the Bhagavad-Gita is essential. As long as ones foundation in spiritual life is not substantiated by the divine revelation originally spoken by the Supreme Lord Krishna known as the Bhagavad-Gita and this knowledge has not been firmly established within the consciousness of a living entity, then regardless of how intelligent or advanced in culture and technology they may appear to be they will not possess a complete and comprehensive understanding of spiritual reality.When we read the Bhagavad-Gita we must also be careful and attentive to read only the commentaries from those authorised by disciplic succession in one of the four authorised Vaisnava schools of knowledge which is well verified in Vedic scriptures. If unaware we make the mistake of reading the comments of those unauthorised outside of disciplic succession we will find ourselves helplessly adrift from the actual truths of the Bhagavad-Gita and hopelessly stranded from the factual meaning of the Bhagavad-Gita.Lord Krishna gives five levels of instructions in the Bhagavad-Gita. The first level is the general teachings for everyone. Then in a very sublime way He gives four more additional levels of teachings each more exalted than the previous. These teachings although extensive are delineated in a condensed form revealing only the essence. How are we to understand what is the essence? The following example will illustrate this for you.When one milks a cow the first thing one does is bring the baby calf to the mother so she can give it a little milk. This first milk is like the general teachings of the Bhagavad-Gita. Afterwards the milkman finishes milking the cow and puts the milk into a pot. This milk is like the confidential teachings of the Bhagavad-Gita. But on the top of this milk there will be some cream. This cream is like the more confidential teachings of the Bhagavad-Gita. Yet if we take and churn the cream it will become butter. This butter is like the most confidential teachings of the Bhagavad-Gita.
