The seat of the Purusha is said to be the heart, hence It "resides in the middle of the body." Although It is limitless and all-pervading, yet in relation to Its abiding-place It is represented as limited in extension, "the size of a thumb." This refers really to the heart, which in shape may be likened to a thumb. Its light is everywhere, yet we see it focused in a lamp and believe it to be there only; similarly, although the life-current flows everywhere in the body, the heart is regarded as peculiarly its seat.Katha 215 · Upanishads · Katha-Upanishad

The same theme, as Christianity, Islam, Buddhism and Taoism address it.
For what if some did not believe? shall their unbelief make the faith of God without effect?Romans 3:3 · Bible · Romans
And when it is said unto them: believe as the people believe, they say: shall we believe as the foolish believe? are not they indeed the foolish? But they know not.Quran 2:13 · Quran · The Cow
Whatever place a faithful, virtuous, celebrated, and wealthy man chooses, there he is respected.Dhp 21.303 · Dhammapada · Miscellaneous
In the highest antiquity, (the people) did not know that there were (their rulers). In the next age they loved them and praised them. In the next they feared them; in the next they despised them. Thus it was that when faith (in the Tao) was deficient (in the rulers) a want of faith in them ensued (in the people).Tao Te Ching 17.1 · Tao Te Ching
