This Guru Purnima, we were blessed by Guruji in a unique manner a book on the yaugika manas (Yogic mind). This book isan articulation of the thoughts of Yogacharya BKS Iyengar and is a study of the mind by the mind to reveal the mysteries and enigma of the mind. The root of the individual mind is the cosmic mind. This mind plays a dual role as it gets polluted when it comes in contact with the pleasure giving objects of the world. It then gets converted into the bhogika mind or the pleasure seeking mind. Such a mind slips into the ocean of infatuation and passion. It is essential to transform the pleasure seeking mind into a disciplined yaugika state of mind by diverting it with the organs of action and senses of perception. This 125 page book explains the constituents, complexities and the 15 facets of the mind; how this mind can make or mar a man. It then explains the role of the practice of ashtanga yoga in transforming the external, pleasure seeking mind into the yogic mind. He explains how the weak individual mind undergoes ‘evolution in evolution and involution in evolution’ to be transformed to the yogic mind. Such a mind is no longer torn between dualities but is released from the magnetic forces of the senses to gravitate towards the consciousness and soul. The clarity of Guruji’s mind is evident in the very lucid manner in which he has eloquently unraveled the enigma of the mind.
