Contemplation: Four Inverted Views, 3

After reviewing the guidelines for practice, take the following as your object of contemplation:

Virtuous man! What is the sign of the self? It is that which is experienced in the minds of sentient beings. Virtuous man, for instance, when a man's body is well coordinated and healthy, he forgets about its existence. However, when his four limbs are sluggish and his body unhealthy and unregulated, then with the slightest treatment of acupuncture and moxa he will become aware of the existence of the self again. Therefore, the self manifests when experience is felt. Virtuous man, even if this man's mind experienced the real of the Tathagata and clearly perceived pure nirvana, it would be but the phenomenon of the self.
