Hinduism

The ancient text followed regarding beards depends on the Deva and other teachings, varying according to whom the devotee worships or follows. 

Many Sadhus, Yogis, or Yoga practitioners keep beards, and represent all situations of life. 

Shaivite ascetics generally have beards, as they are not permitted to own anything, which would include a razor. The beard is also a sign of a nomadic and ascetic lifestyle.

Vaishnava men, typically of the ISKCON sect, are encouraged to be clean-shaven as a sign of cleanliness.
