Like most truth seekers, I was intrigued the first time I heard stories of exceptionally long lived yogis of India. We hear of Trailanga Swami of Varanasi, who supposedly lived to be around 300 years. There is Devraha Baba — his followers believe that he lived for over 250 years. Then there is the deathless Mahavatar Babaji, immortalised in Paramhansa Yogananda’s Autobiography Of A Yogi.
