Yogavashista has the term Yoga in it; it is not Patanjala Yoga, and we don’t find any concept or stanzas that are in Patanjala Yoga

Though Gaudapada Karikas about the Yoga, Sage Gaudapada says that the practice of Yoga is like emptying the mind, like drying the ocean drop by drop with a blade of grass.

Ashtavakra says: - "This is your bondage, that you practice Samadhi or meditation.”

Remaining thoughtless in the waking experience is Yogic Samadhi. Yogic Samadhi is not the Advaitic wisdom.

Brih Upanishad: page 32. "Yoga does not yield truth or liberation."

One who is in Samadhi will not realize that this universe is 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 words Atman and Brahman.

The yogi is unaware of the truth, which is beyond form, time, and space.

By shutting his eyes in Samadhi, the Yogi does not know the universe that 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 to inquire into the nature of the universe and know it as the Soul or consciousness whilst one is awake, and not during sleep or Samadhi.

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 troublesome part of the study of the Advaita. :~Santthosh Kumaar
