Nope, not even a guru or saint will do

As a tree torn from the soil, as a river separated from its source, the human soul wanes when detached from what is greater than itself. Without the ideal, the real turns chaotic; without the universal, the individual becomes accidental. It is the pattern of the impeccable which makes the average possible. It is the attachment to what is spiritually superior: loyalty to a sacred person or idea, devotion to a noble friend or teacher, love for a people or for mankind, which holds our inner life together. But any ideal, human, social, or artistic, if it forms a roof over all of life, shuts us off from the light. Even the palm of one hand may bar the light of the entire sun. Indeed, we must be open to the remote in order to perceive the near. Unless we aspire to the utmost, we shrink to inferiority.—Abraham Joshua Heschel in Moral Grandeur and Spiritual Audacity: Essays, 342
