open dharma

I have set forth the Dhamma without making any distinction of esoteric and exoteric doctrine; there is nothing, Ananda, with regard to the teachings that the Tathagata holds to the last with the closed fist of a teacher who keeps some things back.

Digha Nikaya 16, trans Vajira & Story

I have taught the Dhamma, Ananda, making no "inner" and "outer": the Tathagata has no "teacher’s fist" in respect of doctrines.
