Four vidyadhara levels

Four vidyadhara levels (Tib. rigdzin nampa shyi; Wyl. rig 'dzin rnam pa bzhi) — the four levels of a vidyadhara which are specific to the Dzogchen or Nyingma tradition.

• matured vidyadhara (Tib. namin rigdzin; Wyl. rnam smin rig 'dzin)
• vidyadhara with power over life (Tib. tsewang rigdzin; Wyl. tshe dbang rig 'dzin)
• mahamudra vidyadhara (Tib. chakchen rigdzin; Wyl. phyag chen rig 'dzin)
• spontaneously accomplished vidyadhara (Tib. lhundrup rigdzin; Wyl. lhun grub rig 'dzin)

Related to the Five Paths

According to Longchenpa:

• the matured vidyadhara is on the paths of accumulation and joining, which are known collectively as the stage of aspiring conduct;
• the vidyadhara with power over life has reached the path of seeing;
• the mahamudra vidyadhara is on the path of meditation and
• the spontaneously accomplished vidyadhara is on the path of no-more-learning.

Khenpo Ngakchung states:

• 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.
