Four vidyadhara levels
Four vidyadhara levels (Tib. rig 'dzin rnam pa bzhi)
- matured vidyadhara (Tib. namin rigdzin; rnam smin rig 'dzin)
- vidyadhara with power over life (Tib. tsewang rigdzin; tshe dbang rig 'dzin)
- mahamudra vidyadhara (Tib. chakchen rigdzin; phyag chen rig 'dzin)
- spontaneously accomplished vidyadhara (Tib. lhundrup rigdzin; lhun grub rig 'dzin)
According to Khenpo Ngakchung:
- Those who have the ability to purify the ordinary body with the fire of concentration and transform it into a subtle body acquire the power of immortal life and are called vidyadharas with power over life.
- Those who have not been able to purify their bodies but whose minds have ripened into the deity’s body are known as matured vidyadharas.
- Those who are on the second to the ninth bhumis are mahamudra vidyadharas.
- Then, at the end of the path, at the moment buddhahood is reached, they are spontaneously accomplished vidyadharas.
