I’m not going to comment on Hindu beliefs more than that the belief in one worshipping the self and emptying the mind are not Christian beliefs.
The Hindu scriptures - Vedas - never teach that one should empty the mind; they teach that such a goal is impossible. It’s Buddhism that teaches that. And the “self-worship” should be translated as “Self worship” which means God within our hearts, as the Soul of our souls; not that someone worships their own self.
There is a sub-branch of monism that practices ahangrahopasana (sp?) wherein they worship themselves, but it is a dead end and mistaken understanding. And does not in any way agree with the conclusion of the Bhagavad Gita, Puranas or other Hindu texts.
thank you for the correction
