To keep oneself sharp, lively and quick, spontaneous, and alert to the instant when things arise is considered the Mahayoga by the tantrikas because the success of this small miracle of presence dispenses with all expedients, all techniques, all spiritual practices, all the specific yogas. It is supreme nonpractice, since in the lightning flash of the moment all becoming and all progression on the spiritual path are annihilated. This is the quintessence of Tantrism, of Ch’an, of dzogchen, the Great Seal, or Mahamudra (as the Tibetans and Kashmiris call it).
