We do not have control over the arising of discursive thoughts. Discursive thoughts do not arise according to a schedule; they can and do arise at any time whatsoever. Exactly in accordance with that, meditation needs to be something which can and does arise at any time whatsoever. In other words, given that the arising of discursive thoughts is unscheduled, to have meditation which is liberating we need a meditation in which the arising of discursive thoughts comes together with the meditation, and the meditation comes together with the arising of discursive thoughts.

There are many ways of grasping at the meditative state. Some of you might be so blissful that you feel, ‘Wow, it is so great to feel this. Even if I were to be pricked with a needle right now, it will probably also be a pleasant sensation. It won’t hurt at all.’ According to Dzogchen, it’s perfectly all right to feel blissful. You don’t have to avoid it, but neither should you hold on to it by clinging to or yearning for the feeling of bliss. Instead, recognize that which experiences, and simply allow the bliss to be a reflection in this mirror. Do not fixate upon it at all.
