Sri Amamritanandanatha-ji a kind and modern guru - had studied physics, worked on india's atomics program then had a heart change and renounced his career and took up sri vidya - later set to work creating Devipuram a Sri Vidya town. A nice guy - I called him once and asked him for permission to use the Mahashodashi mantra and he gave me permission and corresponded with me through email until I had it right. I once made a donation but he knew I wasn't working so he returned it. A real guru, unlike the truckload of wannabes see ya guruji they don't make em like you
