In 1984, award-winning American director Lisa Leeman first heard about Paramahansa Yogananda. Her boyfriend at the time told her to read the bestseller, The Autobiography of a Yogi, and laughed, "You’re too empirical." When the 47-year-old did read it, it 'blew her practical mind'. "Even if I didn’t understand it, I realised that many things are possible," she says over the phone from Los Angeles. Little did she know that 34 years later, she would be make a documentary about the great Indian yogi, credited for introducing asanas and meditation to Westerners.
