Vigyan Bhairav Tantra is know for its 108 methods of meditation which I think are not in vedas or not given by patanjali rishi.
So what is the essence of this book, Do we know when it was written (people says it was written by Lord Shiva).
Not a fan of any guru as if now, but Osho and many gurus have been talking about power of now, they just mean that living in the present moment is the way to enlightenment.
How true is that it is different than the knowledge or the way vedas taught us in the path of self realization.
Because they only talk about the power of observation, am i missing tons of things here?
