All the explanations of the scriptures and Gita etc has been done BUT BUT the great teachers have intentionally omitted many key things
It is like giving a recipe for pizza – and omitting cheese , oven setting and duration etc
So when you try to make it based on the book then you will fail
Why do they do that ? So you will have the sense of finding someone accomplished and then when you experience a chakra you will laugh since the description was extremely superficial. All these lives we wasted trying to understand and we suddenly realize the truth is far deeper, brighter, enjoyable than any book.
