By Swami Harshananda
King Bhoja of Dhāreśvara wrote several works out of which one was a vṛtti. It is a brief commentary on the Yogasutras of Patañjali (200 B. C.). This has been named Rājamārttānda or Bhojavrtti. Sometimes another book of the same name is described as a work on astrology and dharmaśāstras. It has been quoted by several later writers.
