Quotes from Samyukta Agama, Vol. 1
Ānanda and the three kinds of scent
Thus have I heard, once, the Buddha was staying in Rājagaha on the mountain Isigili.
At that time the Venerable Ananda was in silent seclusion, when this thought came to him: “Once the World-honored One spoke about three kinds of scent: The scents of roots, stalks and blossoms; and about how there are no better scents than these.
However he said these three can only be sensed with the wind, and cannot be sensed against the wind.” Having had this thought, Ananda rose from his seat, went to the Buddha, and having paid homage at his feet stood to one side. He said to the Buddha: “World-honored One! Just now, while I was in silent seclusion, this thought came to me:
‘Once the World-honored One has spoken about three kinds of scent: The scents of roots, stalks and blossoms; and about how these are the best among all scents. However, he said, these could only be sensed with the wind and not against the wind.’ World-honored One, is there a scent that can be sensed both with and against the wind?”
The Buddha said to Ananda: “There is, there is. In this world there is a good scent that can be sensed both with and against the wind. And what scent? If there is, in a village or town, a man or woman who practices restraint, does not kill, does not steal, does not engage in sexual misconduct, does not lie, and does not drink alcohol, then all devas and all those who have attained divine sight will praise this person. Thus, if in a town or village a man or a woman keeps the five precepts, the scent of the precepts is sensed with and against the wind.”
