At Savatthi. "Bhikkhus, I will teach you about the devas (gods) of the gandhabba order. Listen to that...."
"And what, bhikkhus, are the devas of the gandhabba order? There are, bhikkhus, devas dwelling in the fragrant roots, devas dwelling in the fragrant heartwood, devas dwelling in the fragrant softwood, devas dwelling in fragrant leaves, devas dwelling in fragrant flowers, devas dwelling in fragrant fruits, devas dwelling in fragrant sap and devas dwelling in fragrant scents."
"These bhikkhus are called the devas of the gandhabba order."
Commentary by Bhikkhu Bodhi:
The gandhabbas are associated with fragrant substances, no doubt because the word is based on the stem gandha, meaning scent.
