In the Sadhāyamāna Sutta, the Buddha was wandering with a group of mendicants when some students passed by the Buddha, mocking and jeering.
In the Andhakaraṇa Sutta, the Buddha is heard saying:
Mendicants, these three unskillful thoughts are destroyers of sight, vision, ...
Freedom from illness: the foremost good fortune.
Contentment: the foremost wealth.
Trust: the foremost kinship.
Unbinding: the foremost ease.
~Dhammapada 204
