The Saint or Siddhar bogar visited India in ancient time to the Yoga and medicinal technics in India. He was despic of Kalangi who lived in Kancheepuram of present Tamilnadu. Bogar learned Siddha medicine and Yoga Techniques from Kalangi and many other Siddhars. Bogar mastered Yoga, siddha medicine, Alchemy and Tantric methods and published this book for the pubic. For a long period it was preserved in Palm leaves and published in Book form in 1934 in Chennai. I came across this book in damaging condition. I typed this book from that old book and published already in PDF format and unicode in https://bogar-siddhar.blogspot.com. Now I am publishing this book in Android version for the public use.
