Gayatri The Highest Meditation. Sent Keshavadas’s book on Gayatri joyfully fulfills several functions. Naturally, it elucidates the mantra’s central meaning and significance in its entirety. However, it also describes such practical matters as the use of purifying water rites and the teaching techniques of this japa: sitting posture, time, atmosphere, proper breath control, the use of the fingers of the hand for the various kriya-s, the use of the rosary, the proper pronunciation of the sacreds, and so forth. This will be of tremendous assistance to the new practitioner and will set him on the path of practice.
