I have taught the Dhamma, Ānanda, without making a distinction between inside and outside. The Tathagata has no closed fist of a teacher in regard to the teachings.

It is not always easy to look into one’s own mind. Man generally fights shy of looking too closely into his own mind since the awareness of his own silent evil thinking upsets his good opinion of himself. Continued practice of mindfulness of thoughts will help the disciple to understand that his thoughts are not himself.

An excellent overview of the various kinds of mindfulness meditation practices and why everyone should engage in them.

Protecting oneself, bhikkhus, one protects others; protecting others, one protects oneself.
