Secret instruction (Tib. tri) — one of the prerequisites of sadhana practice.
There are three components needed in order to engage in a specific sadhana practice: the empowerment (Tib. wang), the oral transmission (Tib. lung), and the secret instruction which are all granted or bestowed by a qualified master for each specific practice.
- The empowerment or wang is to mature or ripen us.
- The oral transmission or lung is to connect us.
- The secret instruction or tri is to liberate us.
