Upanshu is a practice that involves quietly repeating a mantra or a deity’s name. It is one of three types of japa, a Sanskrit word that means “muttering.” Upanshu is also a Sanskrit word and means “in a low voice” or “in a whisper.” In upanshu japa, the mantra is murmured so softly that only the yogi him/herself can hear it or distinguish what is being repeated.

Upanshu, in particular, and japa, in general, are practiced to focus the mind spiritually and lead to a deeper state of consciousness. Such practice is an essential aspect of many yoga practices. Japa yoga is a practice that specifically combines yoga with japa as a means to remove mental impurities.
