The tenth chapter of the Bhagavad Gita is Vibhooti Yoga. In this chapter, Krishna reveals Himself as the cause of all causes. He describes His various manifestations and opulences in order to increase Arjuna's Bhakti. Arjuna is fully convinced of Lord's paramount position and proclaims him to be the Supreme Personality. He prays to Krishna to describe more of His divine glories which are like nectar to hear.

Yaksas are a class of demigods who attend on him and guard his wealth.].

Among the great sages I am Bhrgu; of words, I am the single syllable (Om) [Om is the best because it is the name as well as the symbol of Brahman.]. Among rituals I am the ritual of Japa [Japa, muttering prayers-repeating passages from the Vedas, silently repeating names of deities, etc. Rituals often involve killing of animals. But Japa is free from such injury, and hence the best.] of the immovable, the Himalaya.OPEN VERSE
