HONOLULU (AP) — Baba Ram Dass, the 1960s counterculture spiritual leader who experimented with LSD and traveled to India to find enlightenment, returning to share it with Americans, has died. He was 88.

Dass’ foundation, Love Serve Remember, announced late Sunday that the author and spiritual leader died peacefully at his home earlier in the day. No cause of death was given.

He had suffered a severe stroke in 1997 that left him paralyzed on the right side and, for a time, unable to speak. More recently, he underwent hip surgery after he was injured in a fall in November 2008, according to his website.
