Manduka Upanishad:~ Yoga is in the sphere of duality and is unnecessary to one who knows non-duality.
Yoga could in no way bring about wisdom, much less Moksha.
Sage Sankara says: ~ Yoga is not the means of liberation (page 132-133 - Commentary on Brihadaranyaka Upanishad.
Yoga can yield only the duality, because everything that one can do or practice becomes a vanishing 'known.' It yields relative truth based on imagination, which is true from the physical viewpoint of view, not the non-dualistic truth, which is the ultimate reality.
Those who believe yoga is the means for Self-realization will permanently remain in ignorance.
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.
Panchadesi:~ the impossibility of yoga arrives at a successful end to its practices. (P.509 v, 109)
Self-realization is not just a matter of literal or intellectual understanding, but as something that is to be grasped and realized by the individual in his/her own personal realization.
Yogic practices will not help in acquiring Self-knowledge or Brahma Gnana or Atma Gnana. Yogic practices help only in repertory stages to be calm, to have patience and humility, and keep away unwanted thoughts. But yoga is no the means to acquire Self-knowledge or Brahma Gnana or Atma Gnana because yoga is based on the chakras, which are within the body whereas the Soul, the 'Self' has no chakras. After all, it is a formless, timeless, and spaceless existence.
The practice of yoga is not recommended for seekers of truth by Sages Sankara.
The seeker has to be equipped with requisite qualities such as patience, humility ability to focus one's concentration in an intense manner, an ability to discriminate between the Real and the non-Real, and an intense urge for liberation.
It is important to remember that Moksha is not a result of ritualistic practice. Rituals are of the religion and personal Gods based on false Self within the false experience.
Ritualistic practices are meant for the ignorant populace who are incapable of grasping the truth, which is beyond the form, time, and space.
The truth is hidden within the dualistic illusion. Ignorance is the cause of experiencing the dualistic illusion as a reality. : ~ Santthosh Kumaar
