Thus have āgamaĀnāpānasmṛI heard. At one time the Buddha was in Śrāvastī, at the Jeta Grove of Anāthapiṇḍada’s park. At that time, the Bhagavān put on his robe, picked up his bowl, and departed with Rāhula to enter the city walls of Śrāvastī. Then the Bhagavān turned to his right and said to Rāhula, “You should now contemplate the impermanence of form.” Facing him, Rāhula replied, “Thusly, Bhagavān, form is impermanent.” The Bhagavān told Rāhula, “Sensation, conception, synthesis, and discrimination are all impermanent.” Facing him, Rāhula replied, “Thusly, Bhagavān, sensation, conception, synthesis, and discrimination are all impermanent.”

At this time, Venerable Rāhula was mindful, “By what causes and conditions today, on the path to the city walls, has the Bhagavān faced me and admonished me in this manner? I will return now, as I ought not enter the city walls of Śrāvastī to beg for food.” Then Venerable Rāhula promptly returned along the road to the Jeta Grove Monastery. Arriving there with his robe and bowl, he stopped below a tree. Correcting his body and correcting his intention, he sat cross-legged, focusing his energy with one mind. He was mindful of the impermanence of form, and mindful of the impermanence of sensation, conception, synthesis, and discrimination.

Ekottarikāgama 17.1: Ānāpānasmṛti

At this time, the Bhagavān had finished begging for food within the city walls of Śrāvastī. After eating, he returned to the Jeta Grove Monastery and walked about, eventually arriving at the place where Rāhula was. There he addressed Rāhula, saying, “You should cultivate practice with the method of Ānāpānasmṛti. Cultivating practice with this method, every notion of worry and sorrow that you have will come to an end. You are still cultivating practice incorrectly with impurity, and your desires have not yet ended. Rāhula, you should now cultivate practice with a mind of kindness, and all anger will come to an end. Rāhula, you should now cultivate practice with a mind of compassion, and all cruelty will come to an end. Rāhula, you should now cultivate practice with a mind of contentment, and all jealousy will come to an end. Rāhula, you should now cultivate practice with a mind of equality, and all pride will come to an end.”

Ekottarikāgama 17.1: Ānāpānasmṛti

At this time, the Bhagavān faced Rāhula and spoke a gāthā:

Ekottarikāgama 17.1: Ānāpānasmṛti

Not arousing attachment to characteristics, And always in accordance with the Dharma. The one who is wise in a way such as this, Has a name that is renowned everywhere. Together holding the torch of wisdom, The great darkness of ignorance breaks apart. The devas and nāgas pay their respects, Giving praise to the venerable master.

At this time, the bhikṣu Rāhula replied to the Bhagavān with a gāthā:

I will not arouse attachment to characteristics, And will always be in accord with the Dharma. One who is wise in a way such as this, Is still capable of honoring the master.

At this time, after the Bhagavān had given this teaching, he left and returned to his abode of stillness. Then Venerable Rāhula was mindful, “How can one practice Ānāpānasmṛti to eliminate every notion of worry and sorrow?” At this time, Rāhula promptly left his seat and arose, to go to the place where the Bhagavān was. When he had arrived, he bowed his head at the feet of the Bhagavān, and then sat to one side. After sitting, in a moment of purity, he addressed the Bhagavān, saying: “How can one practice Ānāpānasmṛti, to eliminate every notion of worry and sorrow? How can one obtain the great fruit, and taste the sweet nectar?” The Bhagavān addressed Rāhula, saying: “Excellent, excellent, Rāhula! You are thus able to ‘roar the lion’s roar’ before the Tathāgata by asking, ‘How can one cultivate the practice of Ānāpānasmṛti, to eliminate every notion of worry and sorrow? How can one obtain the great fruit, and taste the sweet nectar?’ Now Rāhula, listen carefully. Listen carefully with virtuous mindfulness, because I will explain it to you.” Facing him, Venerable Rāhula replied, “Thusly, Bhagavān,” and waited for the Bhagavān’s instruction.
