In Yogic Samadhi, the yogi is unaware of the universe, and hence of the ultimate truth or Brahman.+

People try to see God through yogic samadhi meditation. And this process of yogic samadhi meditation does not help the seeker to get rid of the ignorance. The ignorance hides the God.

The seeker has to rip open the veil of the ignorance through  Advaitic wisdom  then only the god hidden by the ignorance will be revealed.

There are many paths and practices all over the world. Many are trying to gain bliss through extraneous means of sex and drugs.

Different people try to see God through different means, and naturally, they get different experiences without knowing what God supposed to be in actuality what is the use of seeing and experiencing God. These are different kinds of hallucinations.

There are many self-styled fake gurus who dupe people promise enlightenment, although such enlightenment are nothing but hallucinations.

People flock around them to have some experience also, and thus they have their own group of followers indulge in the propaganda of the power of their guru. 

Even One in a million, through religion, yoga, and meditation does know God what God supposed to be in truth. 

Remember:~

Sage Sankara says: - Yoga is not the means of liberation (page 132-133 - Commentary on Brihadaranyakopanishad.

In Sutra Bashya and Mandukya: - The Samadhi and sleep are identical. 

Brihad Upanishad:  does not advocate Samadhi.

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) 

~This indicates that yoga is not the means to Self-realization.  And yogic Samadhi is not nondual Self-awareness. 

Remember:~

In Yogic Samadhi, the yogi is unaware of the universe, and hence of the ultimate truth or Brahman. 

To talk of Brahman without knowing the meaning of the universe is like utterly meaningless. Nirvikalpa gives only the idea of the Soul but not the truth of the whole.

Yogi thinks of the blankness or thoughtlessness in his samadhis as Brahman.

It is not enough to see a mere blank, Nirvikalpa. You have to see the ‘Soul’ the universal Self, which is the cause of the world in which you exist and it itself is uncaused.

The Soul, the innermost Self is free from ignorance not when it sees nothing at all, as in Yogic Samadhi but only when it sees this entire universe in itself. Hence, there is a need to know

“What is this universe?”

The attention must be drawn to the external world. Advaitic wisdom is the only weapon to bring peace, love and harmony, and universal welfare. This is the highest aim of Advaita to realize the world in its essence is Advaita.

It is no use seeing the personal God everywhere. You must see the Soul, which is present in the form of the consciousness everywhere, and then you will be able to treat the world in which you exist as the consciousness.

Panchadasi: ~ the impossibility of yoga arriving at a successful end to its practices. P.509 v, 109

The ‘Self-realization' through yoga is not philosophic. Every yogi who shuts himself in a cave is not thereby freed from thinking.

Yoga can lead only to temporary peace because the world is subject to change. Only Self- knowledge or Brahma Gnana or Atma Gnana can yield Advaitic awareness in the midst of the form, time, and space. : ~ Santthosh Kumaar
