Notes:
- While Alan Watts and Huston Smith were born outside the U.S., they became central figures in spreading Eastern philosophies within the country.
- Figures like Deepak Chopra (Indian-American) and Eknath Easwaran (India-born, U.S.-based) are also influential but were born abroad.
- Many of these teachers blend Eastern traditions with Western psychology, making their work uniquely accessible to American audiences.
