Dhajaggasutta

sn11.3:9.1 But, mendicants, I say this:

sn11.3:9.2 If you’ve gone to a wilderness, or to the root of a tree, or to an empty hut and you get scared or terrified, just recollect me:

sn11.3:9.3 ‘That Blessed One is perfected, a fully awakened Buddha, accomplished in knowledge and conduct, holy, knower of the world, supreme guide for those fit for training, teacher of gods and humans, awakened, blessed.’

sn11.3:9.4 Then your fear and terror will go away.
