Here is a sketch I created of a concept in Swami Vivekananda’s Jnana Yoga, in the chapter on Realization.
And it is described thusly
“Picture the Self to be then rider and this body the chariot, the intellect to be the charioteer, mind the reins, and the senses the horses. He whose horses are well broken, and whose reins are strong and kept well in the hands of the charioteer (the intellect) reaches the goal which is the state of Him, the Omnipresent. But the man whose horses (the senses) are not controlled, nor the reins (the mind) well managed, goes to destruction. This Atman in all beings does not manifest Himself to the eyes or the senses, but those whose minds have become purified and refined realise Him. Beyond all sound, all sight, beyond form, absolute, beyond all taste and touch, infinite, without beginning and without end, even beyond nature, the Unchangeable; he who realises Him, frees himself from the jaws of death. But it is very difficult. It is, as it were, walking on the edge of a razor; the way is long and perilous, but struggle on, do not despair. Awake, arise, and stop not till the goal is reached.”
