Having been to Bodhgaya a few times, I am always struck by the huge crowds of pilgrims everyday, the intensity of the emotions expressed and felt, and the beauty of the Mahabodhi temple complex.
Reading the suttas, I cannot see any reference to the Buddha returning there during the rest of his life after enlightenment.
He spent many Rains Retreats in other places, and there are important suttas associated with them - but there seems to be no further return to Bodhgaya.
Does anyone have any references showing that he did? And, if he didn't, why not?
