Maharishi, or maharsi, is a Sanskrit word typically used as an honorary title which is added onto the name of an enlightened spiritual teacher. It can be applied to an awakened yogi and has been bestowed upon many figures who were central to the yoga tradition.
The term is derived from the roots maha, meaning “great,” and rsi, meaning “seer.” It has been used in English since the 18th century and usually refers to a Hindu or Vedic guru with great mystical knowledge.
Shishya is the concept of a spiritual guide or teacher enlightening a disciple through oral teachings. This is a common idea in religions such as Buddhism and Hinduism.
Individuals seeking to learn the spiritual path of yoga may engage in shishya with a trusted guru or teacher.
Jagadguru is a term used for a guru whose influence on the world has the power to transform it. The term – literally meaning “guru of the world” – comes from the Sanskrit, jagat, meaning “world,” “Earth,” “the cosmos” or “mankind”; and guru, which means “teacher” and usually refers to a spiritual master.
The title of jagadguru is typically used in traditional orthodox Hinduism, particularly for acaryas (spiritual teachers) in the Vedanta school of thought who have written commentaries on the scriptures.
