There are three forms of enlightened life:

At the foundation is life upon a wild beast— only that the inner self stays awake, and that innerness is joined by a great light from Above, so that eyes stay on the road, with mind, words and limbs working together to reach their destination.

There are many levels to this rung, but all are within the reach of every person.

Then there is a person within whom burns a holy fire of desire for the Oneness of the Infinite Light. With this fire, he overwhelms the fire of earthly passion, until it is diminished to no more than a faint flicker.

This again knows many levels, but all within the realm of the tzaddik—something not every person is meant to attain in this life.

And then there is an ultimate point: Where the fire of earthly passion becomes itself a G‑dly force. Then there will not be any more darkness, for we will have revealed how all darkness shines.

This is the stage of a time to come, but it is being formed in the here and now, out of our struggle with that wild beast and the harnessing of its passions.
