The Long Āgama Sūtra 16.4

16.4

爾時，世尊時到著衣持鉢，入城乞食。時，羅閱祇城內有長者子，名曰善生，清旦出城，詣園遊觀，初沐浴訖，舉身皆濕，向諸方禮，東、西、南、北、上、下諸方，皆悉周遍。

It was then that the Bhagavān put on his robe and took his bowl into the city to solicit alms. At the time, there was a prominent man’s son named Sujata in Rājagṛha. Early in the morning, he left the city to go for a walk in a park. He bathed first, wetting his entire body. He then bowed in all directions around him: To the east, west, south, north, above, and below.
