Manduka Upanishads: ~ “Those that want Brahman will not practice control of the mind. That is Yoga for duffers.+

Some gurus propagate by control of the senses leads to Self-realization. By controlling the senses the ignorance will not vanish. Some yogis say to control the mind.

By controlling the senses the ignorance will not vanish. It is foolish to venture to control the mind without knowing what is this mind’ in actuality.

Manduka Upanishads: ~ “Those that want Brahman will not practice control of the mind.  That is Yoga for duffers. The others will inquire and practice discrimination. (p.231)

Without getting rid of ignorance, the world in which you exist prevails as reality.

Thus, it is necessary to realize that the ‘Self’ is not you but the Self is the invisible Soul, which is present in the form of consciousness. 

The invisible Soul has no organs because the Soul is formless, timeless, and spaceless existence.

Ashtavakra Gita: ~ “The fool tries to control the mind with the mind - what folly! The wise one delights in the Self alone. There is no mind to master.

Yogis say they control the Mind. They think the mind is an organ within the body. Thus, yoga is limited to form, time, and space, whereas the truth is hidden by the illusory form, time, and space.

Remember:~

It is high time for them to realize the mind is not within the body, but their body and the world are within the mind.

Without knowing what this mind is, it is impossible to realize the truth, which is beyond form, time, and space.

The ‘I’ is present only when the mind is present. The mind is present in the form of the universe. The universe appears as the waking or the dream (duality) and disappears as deep sleep (nonduality). The one that becomes dual and nondual is consciousness.

Thus, all three states are nothing but consciousness. Consciousness alone is real, and all the three states are merely an illusion. When the conviction about the consciousness becomes firm, then it leads to Advaitic awareness in the midst of the duality.

Thus, it is necessary to have a perfect understanding of 'what is ‘what’ to realize the truth, which is beyond form, time, and space. : ~ Santthosh Kumaar
