Chiang Dao Cave village, close to Chiang Dao Nest and Malee's, has a Hindu style Ashram, called Matadee Ashram Rishi Mae Yogi, where you can meditate, or learn meditation from Guru Nirantra and Mata.
The Guru attracts devotees from across the globe. People have made claims about his healing powers.
Unfortunately neither the Guru nor Mata speak much English, but enough to get by.
They hold two meditation sessions daily, and people from all faiths are welcome.

6-7am Daily Morning OMN Meditation
6-7pm Evening Kundalini Meditation
Attending each session for at least three consecutive days is recommended, but attendees are welcome anytime.
There is no charge although donations are appreciated. For more info click here.
Meditation at Wat Tham Pha Plong is also possible. Please see section on Temples.
