The external worlds are created by the lower mind. By controlling the lower mind, the external world is finished. Then meditating on the One Reality, the Yogi becomes that Reality or Brahma. He is not affected by matter, space or time. He is above all.
All things in the world are perceived by mind. When the mind is controlled there remains no duality. When the mind is merged
in the Atma, that state is the Absolute, and is Satchitanada (truth, wisdom, bliss).

The Nada Practice:
The Great Yogin Garakhnath has given out the practice of Nada to help those who are unable to realize the pure truth.
The Yogi should sit in the Sidhasan and practice the Shambhavi Mudra, and should listen with fixed mind to the sound of the self, which will be heard in the right side of the head. The sounds will be ten--from the ocean roar to a very subtle sound--but Yogi should keep the mind fixed on Nada which is the goal. When the Yogi is sitting in Sidhasan practicing Shambhavi with Yoni Mudra, he should force the Prana to the heart center, as the sound begins there. When Prana becomes one with the Nada, then the Yogi should move it to the Vishudha Chakra. As soon as Yogi succeeds in taking the Nada with Prana to the Vishudha Chakra, he will become like Devas, and the Brahmanada (Divine Bliss) will surely follow.
From the Vishudha Chakra Yogi should forcibly take the Prana and the Nada to the Ajna Chakra. This is the source of all Sidhis. Reaching here the Yogi controls all the finer forces of nature and mental knowledge. He arises above nature's elements and mind, and is one with Atma, above the world's miseries. His mind is listening to the inner sound of the Nada.--it is the blessed joy that can be known by one who has attained that state.
One state more remains for the Yogi; that is going up from the Ajna Chakra to the Sir Chakra or the Thousand Petal Lotus. In Yogi will hear the sound of flutes. He has this Lotus, Yogi will hear the sound of flutes. He has then reached the highest state of Bliss. He is equal to God, as he can create and destroy any material thing, if he so wishes. But creation and destruction are not the object of the Yogi; he wants to be liberated, and in this State he is liberation itself.
"Practice of Nada is most easy, even a feeble minded person can succeed by daily practice. The practitioner will soon start to feel the joy that arises by the Nada in the heart. That joy cannot be explained by words as it is Divine Joy, above the reach of
mental knowledge.
Sick and suffering humanity should practice Shambhavi, that they could hear the Nada sound, or the Inner Voice.
