Ch. 2 Yoga of Discernment of Reality (Part 8)
There are several tiers of instruction in the Bhagavad-gītā from the level of "patraṃ puṣpaṃ phalaṃ toyam" (offering a leaf, flower, fruit or water) to the level of nistraiguṇya (being beyond the three qualities). Not all of us can follow these teachings at all times. It is like a library wherein we select what we need. Though there are hundreds of lessons, it is up to us to choose what fits us. One’s itch cannot be relieved by another person. Only the experiencer knows what and where the itch is.
