Abandon your notions of the past, without attributing a temporal sequence! Cut off your mental associations regarding the future, without anticipation! Rest in a spacious modality, without clinging to [the thoughts of] the present. Do not meditate at all, since there is nothing upon which to meditate. Instead, revelation will come through undistracted mindfulness — Since there is nothing by which you can be distracted. Padmasambhava, The Tibetan Book of the Dead
