I've gotten some preliminary information back, more details to follow. Amma's ashram in Kerela is highly regarded and costs $3 a day for room and board and $3 a day for PK. Delhi used to be the place to go for PK, cost €90 a day (all inclusive rate), but now Hyderabad is preferred, cost is €70 (all inclusive rate).
Please stand by for directions and contact information.
