Dhajagga Sutta (SN 11.3 )

“In a forest, at the foot of a tree,
Or in an empty hut, O bhikkhus,
You should recollect the Buddha:
No fear will then arise in you.

But if you cannot recall the Buddha,
Best in the world, the bull of men,
Then you should recall the Dhamma,
Emancipating, well expounded.

But if you cannot recall the Dhamma,
Emancipating, well expounded,
Then you should recall the Saṅgha,
The unsurpassed field of merit.

For those who thus recall the Buddha,
The Dhamma, and the Saṅgha, bhikkhus,
No fear or trepidation will arise,
Nor any grisly terror.”
