According to Yogananda, Mahavatar Babaji is a highly evolved spiritual master who has been living in the Himalayas for centuries. He is said to be a master of yoga and meditation, and he is said to have the power to heal and to bestow spiritual gifts.

Yogananda's account of Mahavatar Babaji is fascinating, and it has inspired many people to seek out their own spiritual path. However, it is important to remember that Yogananda's account is a personal one, and it is not necessarily accurate. There is no way to know for sure whether or not Mahavatar Babaji exists, or whether or not he is the spiritual master that Yogananda describes.

Ultimately, whether or not you believe in Mahavatar Babaji is a matter of personal faith. There is no right or wrong answer, and it is up to each individual to decide what they believe.

If you are interested in learning more about Mahavatar Babaji, I recommend reading Paramahansa Yogananda's Autobiography of a Yogi. This book is a classic of spiritual literature, and it provides a detailed account of Yogananda's encounters with Mahavatar Babaji.
