Problems of Mysticism and Its Symbolism Book

I was impressed by the ending of the introduction. I think the last paragraph hits the nail on the head.
I happened to bump into a passage from taoist literature which reminded me of Franke's point in the introduction:

"Do you wish to free yourself of mental and emotional knots and become one with the Tao?
If so, there are two paths available to you.
The first is the path of acceptance. Affirm everyone and everything. Freely extend your goodwill and
virtue in every direction, regardless of circumstances. Embrace all things as part of the Harmonious Oneness, and then you will begin to perceive it.
The second path is that of denial. Recognize that everything you see and think is a falsehood, an illusion, a veil over the truth. Peel all the veils away, and you will arrive at the Oneness.
Though these paths are entirely different, they will deliver you to the same place: spontaneous awareness of the Great Oneness."

This particular point is also made in Zen Buddhism and by Nisargadatta.
