The essence of thoughts that suddenly arise is without any nature. Do not inhibit their appearance in any way, and without thinking of any essence, let them arise clearly, nakedly, and vividly. Likewise, if one thought arises, observe its nature, and if two arise, observe their nature. Thus, whatever thoughts arise, let them go without holding onto them. Let them remain as fragments. Release them unimpededly. Be naked without an object. Release them without grasping. This is close to becoming a Buddha. This is the self-extinction of samsara, samsara is overwhelmed, samsara is disempowered, and samsara is exhausted. Knowledge of the path of method and wisdom, appearances and emptiness, the gradual stages, the common and special paths, and the 84.000 entrances to the Dharma is made perfectly complete and fulfilled in an instant. This is self-arisen, for it is present like that in the very nature [of awareness]. Natural liberation is the essence of all the stainless paths, and it bears the essence of emptiness and compassion.
