Takdrol (Wyl. btags grol) is one of the “five methods that lead to liberation without the need for meditation”. These are sometimes given as:
Numerous kinds of takdrol exist: many are mantras in diagrams (Skt. yantra; Tib. sung khor, Wyl. srung 'khor) 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.
