The human body has a great number of Nadis, the three main ones,--Ida and Pin-gala on each side of the spine, the Sushumna in the middle. The Prana moves thru the Ida and Pingala only; the Sushumna being closed. When Yogi learns the secret of controlling the Prana and Apana, then he can awaken the Kundalini, and force the Prana to go thru the Sushumna. When this has been accomplished--Samadhi follows. All other means are waste of time. Thus Yogi should not follow other means if he desires to awaken the Kundalini and reach Samadhi.
The mind is made to move by two things, the Prana and desire. If Prana is controlled, desire is also controlled. Therefore, the Prana and mind are as one. As long as the mind is not mastered, so long the senses are not mastered. When the three are controlled, then the Yoga can hold them on any Chakra, and awaken or move the Kundalini. By
control of the Prana and mind the Yogi gains strength; by this strength he arises above all diseases. So Yogi should practice Pranayama and the Mudras to master Prana.
The mind is the master of the organs of sense, the Prana is the master of the mind. When the Prana and the mind are under control the Yogi attains blessed peace, which can only be known by experience.
The lower mind is ignorance itself. When the mind is controlled, ignorance, which is the Mother of Maya (illusion), dies. The Yogi attains Samadhi or the state of Brahma.
Every one wishes to attain the Laya Yoga, but it is difficult to attain. To do so the Shambhavi Mudra is the best to practice. This Mudra cannot be attained until the Prana and the mind are controlled; then Shambhavi Mudra should be practiced as it raises the Yogi above time, matter, space and ether. He controls the power of nature's forces, as levitation and walking on water, and he can live as long as he desires. but this is not the object of the Hindu Yogis. Their object is not to attain wonderful powers. but Seedless Samadhi--the Brahmic state--which is
above all other states; it is divine peace and common to all.
When the Yogi succeeds in controlling Prana, from the Ida and Pingala Nadis, and makes it go thru the Sushumna, he has reached the state wherein he experiences TRUTH, which is the Light of Lights, and is the Source of All. This is the goal of all.
Yogis practice different Mudras to control Prana. When Prana is controlled and made to move thru the Sushumna, the state of Samadhi follows. This is the correct method When Yogi desires to cheat death and time, he raises the Prana up to the Ajna Chakra, placing the Prana and the mind in the , then by steady meditation Yogi moves the Kundalini. He then places the Atma in the Brahma and Brahma in the . He is then in Samadhi--ALL in ALL.
