it is an amazing book about so many amazing Gurus....Yogananda founded the Self Realization Fellowship (SRF) in the USA

you can check their website ...but off course do not mix ayp with SRF practices

lately i have been listening to some kirtan chanted by SRF monks and it is so strong...i experience some scenery like goose bumps and itching at my jnana chakra
