'Those that want the ultimate truth or Brahman will not practice control of the mind.+

Manduka( p.231):~  'Those that want the ultimate truth or Brahman will not practice control of the mind. 

Control of the senses does not yield nondualistic or Advaitic wisdom. The practice of Ashtanga-yoga is not the means to acquire Self-knowledge. 

The difference between Self-knowledge and meditation is that the former depends on knowledge of the Soul, the ‘Self’, whereas the latter depends on the yogi’s own feelings and experience.  Self-knowledge is Soulcentric-knowledge whereas the yogis’ experience is egocentric. 

It is only the yogi who is striving to control his mind, who refrains from worldly duties, through fear of being distracted from his yogic Samadhi. 

The Soul is the Self. The Soul is present in the form of consciousness. The whole universe and all its contents are created out of the Soul or consciousness. Thus, there is no second thing that exists other than consciousness. 

Thus, the consciousness is the ultimate truth or Brahman. Once one knows what gold is, it is not necessary for him to see a pot again when the word 'gold' is uttered and its meaning sought. Similarly, once one knows Brahman, its true nature will always be known to him. Everything that one sees will be seen by him as ordinary people, but it will also be known to him in its true nature as Brahman.

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

The meditation, meditator, and the world in which meditation is performed is an illusion created out of single clay. That single clay is the Soul, which is present in the form of consciousness. Knowledge of the single stuff is Self-knowledge or Brahma Gnana or Atma Gnana. 

Self-knowledge or Brahma Gnana or Atma Gnana leads to Self-awareness. In Self-awareness, the Soul, the 'Self' remains in its own awareness in the midst of the dualistic illusion. Self-awareness is real meditation. Thus, Self-awareness is real meditation. Mediation is the nature of the Soul, the Self.

Meditation always means the critical analysis of the Self to get rid of ignorance. 

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. 

People dip into meditation, but they do not understand that that is only one half of the truth and that this dipping is also a mental discipline for them to understand the true nature of the external universe, which understanding they must next get if they are to become a Gnani. 

Nondualistic or Advaitic wisdom requires investigation into the nature of the mind. The mind is present in the form of the universe. 

The universe appears as waking or dream (duality) and disappears as deep sleep (nonduality). One has to the fact that the mind rises and subsides from the formless source, which is the Soul. 

The Soul is present in the form of consciousness. The Soul is the Self. Therefore, one has to learn to judge the truth from the standpoint of the source from where the mind rises and subsides, not from the standpoint of the waking entity, which is the false self within the false experience. : ~ Santthosh Kumaar
