A Timeless Evolution of Consciousness !
In the human brain exists the formation of a “swan in flight”. In the head is the Corpus Callosum and the ventricles which are located in the mid-brain.
When a Hamsa Yogi through meditation and pranayama activates the Kundalini energy, then these ventricles in the brain open up. The two petals in the Agaya chakra open (corresponding to the pituitary gland). The Yogi at this stage experiences Hamsa consciousness – being breathed by the Divine Indweller, the universal Prana.
As the Yogi progresses in the Hamsa meditation, the subtle fibers in the corona radiata light up with divine energy and effulgence. These radiant fibers spread in the Sahasrara chakra. The Hamsa Nath Yogi’s Sarvikalpa consciousness then expands to the Paramhamsa Nath Yogi’s state of Nirvikalpa consciousness. An expansion of awareness beyond the “I-ness” of humanity takes place.
The Sushumna channel in the spinal chord is the highway through which the Kundalini energy travels and the evolution of consciousness takes place. A still greater state than Paramhamsa is that of the SiddhaNath Yogi, a jeevan mukta. When the mighty Hamsa soul rests in absolute “zero” in the Cave of Brahma, spreading its wings of consciousness to experience the Divinity of creation, one is the SiddhaNath Yogi.
Then the majestic soul proceeds to a loftier state of spiritual awareness beyond the reckoning of mortals where one transfigures oneself into an AvadhootNath Yogi and experiences the total divinity of and beyond creation, gaining the ultimate knowledge of ‘Tat Tvam Asi’ (That Thou Art). The Yogi then merges into Niranjan, the final Nirvana, and is the conqueror, the supreme Jina, having attained the enlightenment of the Buddha and the Christ. This AvadhootNath Yogi returns to the world no more. If, under rare circumstances this Yogi ever does return, it will be as the descent of divinity in flesh and form, and as AvatarNath Yogeshwar.
Note: The Cave of Brahma is located in the center of the skull, with the thalamus glands as its wall, the hypothalamus as its floor and the plexus of the third choroid ventricle as its roof. Within the cave is the spring of life, the aquaduct from which flows forth the cerebrospinal fluid upon which floats the Hamsa swan-like Corpus Callosum.
