Mantra and yantra was the theme of the satsangs in March 2010 during Chaitra Navaratri. Here, Swami Niranjan traces the origin and nature of mantra and yantra and how they act as a link between the individual and the cosmos. These satsangs introduce both the theoretical and practical aspects of a vast subject, providing aspirants with an understanding of mantra and yantra as tools for sadhana.
