Takdrol
Takdrol is one of the “five methods that lead to liberation without the need for meditation”. These are sometimes given as: liberation through seeing (chakras); liberation on hearing (mantra); liberation by tasting (amrita); liberation by touch (mudra or takdrol); and liberation by recollection or thinking (phowa).
Numerous kinds of takdrol exist: many are mantras in diagrams related to the Dzogchen teachings, and others belong to the tantras. The takdrol can form part of a more detailed empowerment, or it can be given independently as a simple empowerment on its own. Sometimes a text of a tantra is used as a takdrol and worn, for example, in a locket on the top of the head. (Information kindly given by Tulku Thondup Rinpoche).
