At that time Tapussa and Bhallika, two merchants, came traveling on the road near by,
and when they saw the great samana, majestic and full of peace,
they approached him respectfully and offered him rice cakes and honey. [2]

This was the first food that the Enlightened One ate after he attained Buddhahood. [3]

And the Buddha addressed them and pointed out to them the way of salvation.
The two merchants, conceiving in their minds the holiness of the conqueror of Mara,
bowed down in reverence and said:
"We take our refuge, Lord, in the Blessed One and in the Dharma." [4]

Tapussa and Bhallika were the first that became followers of the Buddha
and they were lay disciples. [5]
