Subhuti was Buddha's disciple. He was able to understand the potency of emptiness, the viewpoint that nothing exists except in its relationship of subjectivity and objectivity.
One day Subhuti, in a mood of sublime emptiness, was sitting under a tree. Flowers began to fall about him.
"We are praising you for your discourse on emptiness," the gods whispered to him.
"But I have not spoken of emptiness," said Subhuti.
"You have not spoken of emptiness, we have not heard emptiness," responded the gods. "This is true emptiness." And blossoms showered upon Subhuto as rain.
