Manduka Upanishad:~ Yoga is in the sphere of duality and is unnecessary to one who knows non-duality
In Gita Chap.IV where Lord Krishna says: ~ "This yoga has been lost for ages" the word yoga refers to Gnana Yoga, not other yogas: the force of the word this is to point this out.
Lord Krishna describes some of the other yogas but devotes this chapter separately to Gnana Yoga. So one sees even in those ancient days people did not care for Advaita; they wanted religion; hence Gnana got lost. That is why Krishna calls it "the supreme secret." Krishna points out that the yoga must-see "Brahman in action."
Gita Chap.IV: "He who achieves perfection in Yoga finds the Self in time." This means that after his yoga is finished, he begins the inquiry into ultimate truth, and in due course, this inquiry produces the realization of the universal Spirit as the result.
Thus, yogi when he finds the yoga is inadequate and useless to realize the 'Self' he must drop yoga and take up the path of Gnana.
Brih Upanishad: page 32. "Yoga does not yield truth or liberation."
One who is in Samadhi will not know that this universe as consciousness; therefore yoga is not the means to Self- knowledge or Brahma Gnana or Atma Gnana.
In Samadhi the yogi knows nothing, sees no universe; so if there is nothing but blankness. The blankness is not the Advaitic wisdom.
The yogi does not know the nature of the universe. If the universe is not seen in the Samadhi then there is no need to use the word Atman and Brahman. The yogi is unaware of the truth, which is beyond the form, time, and space.
By shutting his eyes in Samadhi, the yogi does not know the universe, which confronts him. Hence the universe can't be known as the Soul or the consciousness through yoga.
One is in a non-dual condition in deep sleep or Samadhi, One without a second, true, but he did not know it at the time. He says only in the waking experience afterward. Hence, there must be an inquiry so that you find non-duality whilst you are awake so that you can see nonduality at the time not afterward. Hence, too the need for inquiring into the nature of the universe and knowing it as the Soul or the consciousness whilst one is awake, and not during sleep or Samadhi.
Chandogya Upanishad: ~ One who meditates upon and realizes the Self discovers that everything in the cosmos-- energy and space, fire and water, name and form, birth and death, mind and will, word and deed, mantrams and meditation--all come from the Self.
Advaitic truth is the ultimate truth. Yogis, mystics, and religious teachers do not accept the path of wisdom because it pries into the truth, the source, and the validity of the knowledge they claim. Therefore, it is the most difficult part of the study of the Advaita.
Remember:~
Sage Sankara says in Viveka Chudamani:- VC- 56-Neither by Yoga, nor by Sankhya, nor by work nor by learning, but by the realization of one's identity with Brahman is Liberation possible, and by no other means.
Sage Sankara in the commentary to "Brahma Sutras:- " "The highest beatitude is not to be attained by Yoga." (Sacred Books of East Series page 298 Vol.1.) And he also says Samadhi is the same as sleep (p.312) ---which indicates that yoga is not the means to Self-realization. And yogic Samadhi is not nondual Self-awareness.
Panchadasi: - the impossibility of yoga arrives at a successful end to its practices. (P.509 v, 109)
Bhagavan Buddha gave up his austerities of yoga as impossible and useless. (Page.70/71 "Buddhism in Translation” by Warren)
Bhagavan Buddha got enlightenment only after he gave up Yoga. Unless one exercises his reason--there is no chance of getting the truth.
There is no need for any practice to realize the ultimate truth or Brahman or God in truth. Perfect understanding assimilation of ‘what is what’ is very much necessary to realize the ultimate truth or Brahman, which is God. :~Santthosh Kumaar.
