Mind is the cause of bondage and liberation
'It is the mind, alone, that is the cause of people's bondage and liberation. One whose mind is devoted to the world (of objects) is bound. One whose mind is not devoted to the world (of objects) is liberated. So it is declared (by the wise)!'
- Amrtabindu Upanishad 2
No invocations, rites or paraphernalia required. Just the elimination of mindstuff's concoctions.
