i was just about to post a review about my pranayama experience that i noticed your message. Sorry to hear about your cousin.
You should definately explore the earthpulse sleep on command. it's now available in india via Amazon india.
this is a magnetic sleep machine that uses PEMF therapy to practically erase Depression and give great sleep at the same time.
it's been around from past 10 years and i've been using from 2 years.
