The ancient Indian scriptures mention that Lord Brahma - the omnipresent supreme creator had attained the supreme knowledge of Gayatri which is said to be the origin of all the spiritual, conscious, unconscious and super conscious faculties, cosmic energy and material existence. The cosmic power of Gayatri used for the creation and perceptible realization of this universe is named as Savitri. The philosophy and subtle science of Gayatri aims at the collective awakening of the righteous intellect, divine sentiments, altruist creativity and eminence. The science of Savitri deals with the origin and proper utilization of matter and energy.

Gurudev Shri Ram Sharma Acharya had successfully practiced the highest kind of spiritual endeavors (sadhanas) of Gayatri and Savitri . He had performed 24 Maha Purashcharanas each of 24 hundred thousands japa - anushthana of Gayatri Mantra while observing ascetic disciplines for twenty four consecutive years. He also endeavored specific spiritual experiments of Savitri Sadhana - involving activation and extraction of the subtle power and vital energy of the Sun God along with the arduous sadhanas of Gayatri anushthanas. Details of the origin, knowledge and spiritual science of Gayatri and of Gurudev's sadhanas of Gayatri are presented in the volumes numbered 9 to 14 of this series.

Volume 1 of this series presents a sketch of his life, his experiences in the Himalayas and the great mission accomplished by him after successful completion of these sadhanas which are defined in the Indian scriptures as the supreme and ultimate endeavors of spiritual transmutation. The present volume focuses on Gurudev's Savitri Sadhana which also incorporated his unique spiritual experiments on activation and transmutation of the grand vital force - Kundalini, the 'serpentine power'. These sadhanas, popularly known as Kundalini Jagarana Sadhanas, correspond to the time-testing, difficult spiritual practices of successive penetration of the shat chakras (extra sensory power centers in the endocrine system) and opening of the three granthis (subtle knots along the spinal column) to activate the eternal source of immense vital power and pull it upwards to charge the sahastrara. This sadhana is supposed to be risky and is attempted only by experienced sadhakas under authentic guidance. The success of Kundalini Jagarana sublimates the vital force into a source of supernatural potentials and opens up the ways of spiritual culmination of the self up to the highest realms of divinity.

Ancient scriptures of yoga describe the sushumna nadi - an extrasensory channel of vital energy which is considered to be spread latently in the inner core of the spinal column in the shape of a serpent having its 'tail' coiled in three and a half turns of a spiral inside the muladhara chakra (the bottom most of the shat chakras) and has thousand 'hoods' in the sahastrara (extrasensory region in the reticular activating system of the human brain above the agya chakra).

The ida chakras and pingla nadis - subtle canals within the sensory and motor control columns parallel to the sushumna nadi, along its left and right sides respectively, help harmonize and control the upward flow of the currents of prana (life force). Three latent knots (granthis) of supernatural sources of power are also described to exist along the sushumna nadi; these are - Brahma Granthi near the muladhara chakra (extra sensory power center in the inner region of pelvic plexus); Vishnu Granthi near the suarya chakra (extra sensory power center in the middle region, above the navel, of the spinal column); and the Rudra Granthi in the inner core of the central region of the brain. There is also a mention of pancha mahakosha - five extrasensory ‘shells’ which cover the gross, subtle and astral bodies of an individual and bring the existence of the soul into being...
