Lai was born in Taiwan to devout Buddhist parents and was thus introduced to Buddhism at an early age. In 1991, she combined Eastern and Western ideas about health care and established the Lapis Lazuli Light Institute in California. She also began making trips around the US and to Taiwan, Hong Kong, mainland China and Singapore to talk about and promote her concept of holistic healthcare involving the body, mind and spirit.
