[ 4 ] explain the expressions of the text with the help of the available works on Haṭhayoga and Rājayoga, yet we do not hesitate to declare that the significance of some of the expressions remains still to be determined. The work, we believe, will delight all lovers of yoga and inspire them to run on the path of yoga with undivided attention. R. S. Bhattacharya
