The faculty of trance ( Samadhi ) becomes perfect in him who dedicates all his powers to Ishvara. By this he knows all that he desires to know, just as it is in reality, in another place, in another body or at another time . Then his intellect knows everything as it is.
Yogis not yet free from the world revolve back again (to the world) even from the high sphere of Brahma (union with God in samadhi). But on entering into Me (the transcendental Spirit) there is no rebirth, O son of Kunti (Arjuna)!
The followers of Advaita Vedanta maintain that creation, preservation, and dissolution, the individual ego, the external world, all these are manifestations of the Eternal Energy (Shakti). They also say that when these are properly analyzed, they appear as dreams, that the Absolute Brahman alone is the Reality, and all else is unreal. Even Eternal Energy (Shakti) is like a dream, unreal, but you may analyze and discriminate thousands of times, you cannot transcend the realm of Divine Energy (Shakti) unless you have reached the highest state of samadhi or Superconsciousness.ramakrishna
When your intellect transcends the mire of delusion, then you will attain to disgust of what has been heard and what is yet to be heard. When, perplexed by what you have heard, you stand immovable in samadhi , with steady intellect, then you will attain yoga .
