In this volume, which is part of Pandit Motilal Shastri’s commentaries on Bhagvad Gita, the concept of upasana or worship has been explained. He has defined four main forms of worship and eight characteristics of worship. He has also presented the scientific character of `dasha vidya` in this volume besides strong evidence in support of idol worship. Shastriji has laid emphasis on love or devotion as the essential ingredient of worship. He has explained five stages of love—respect, maternal love, romance, desire and lust.
