Some Sutta, can't go wrong with that:)
SN 11.3
Dhajagga Sutta: The Top of the Standard
On one occasion the Blessed One was staying at Jeta's Grove, Anathapindika's monastery. There he addressed the monks, "Monks!"
"Yes, lord," the monks responded to him.
The Blessed One said, "Monks, once the devas & asuras were arrayed for battle. Then Sakka, the chief of the devas, addressed the devas of the Thirty-three: 'If, dear sirs, when the devas have gone into battle, there should arise fear, terror, or horripilation, then on that occasion you should catch sight of the top of my standard. For when you have caught sight of the top of my standard, whatever fear, terror, or horripilation there is will be abandoned.
...
"But, monks, when the top of the deva-chief Sakka's standard is caught sight of, or when the top of the deva-king Pajapati's standard is caught sight of, or when the top of the deva-king Varuna's standard is caught sight of, or when the top of the deva-king Isana's standard is caught sight of, whatever fear, terror, or horripilation there is may be abandoned or may not be abandoned. Why is that? Because Sakka the chief of the devas is not devoid of passion, not devoid of aversion, not devoid of delusion. He feels fear, feels terror, feels dread. He runs away.
"But I tell you this: If — when you have gone into the wilderness, to the shade of a tree, or to an empty building — there should arise fear, terror, or horripilation, then on that occasion you should recollect me: 'Indeed, the Blessed One is worthy & rightly self-awakened, consummate in knowledge & conduct, well-gone, an expert with regard to the world, unexcelled as a trainer for those people fit to be tamed, the Teacher of divine & human beings, awakened, blessed.' For when you have recollected me, whatever fear, terror, or horripilation there is will be abandoned.
...
Why is that? Because the Tathagata — worthy & rightly self-awakened — is devoid of passion, devoid of aversion, devoid of delusion. He feels no fear, feels no terror, feels no dread. He doesn't run away."

AN 11.12
Mahanama Sutta: To Mahanama (1)
...
[1] "There is the case where you recollect the Tathagata: 'Indeed, the Blessed One is worthy and rightly self-awakened, consummate in knowledge & conduct, well-gone, an expert with regard to the world, unexcelled as a trainer for those people fit to be tamed, the Teacher of divine & human beings, awakened, blessed.' At any time when a disciple of the noble ones is recollecting the Tathagata, his mind is not overcome with passion, not overcome with aversion, not overcome with delusion. His mind heads straight, based on the Tathagata. And when the mind is headed straight, the disciple of the noble ones gains a sense of the goal, gains a sense of the Dhamma, gains joy connected with the Dhamma. In one who is joyful, rapture arises. In one who is rapturous, the body grows calm. One whose body is calmed experiences ease. In one at ease, the mind becomes concentrated.
