What is the meaning of the divine instinct?

They that see the Real in the midst of this Unreal, they that behold life in the midst of this death, they that know the One in all the changing manifoldness of this universe, unto them belongs eternal peace—unto none else, unto none else.

—The Hindu Upanishads

He to whom all things are one, and who draws all things to one, and sees all things in one, is able to be stable in heart and to remain at peace in God.

—De Imitatione Christi

They have a quickened Divine instinct. When this state is reached—or even when it is approached, the Eternal Word, that is, the Universal Divine Manifestation has spoken to him who has reached or approached this state.
