Here are some selected verses from Jnaneshwar, a 13th century Indian mystic.

Amritanubhav (The Nectar of Mystical Experience)

Chapter One: The Union of Shiva and Shakti

I offer obeisance to the God and Goddess,
The limitless primal parents of the universe.

They are not entirely the same,
Nor are they not the same.
We cannot say exactly what they are.

How sweet is their union!
The whole world is too small to contain them,
Yet they live happily in the smallest particle.

When He awakes, the whole house disappears,
And nothing at all is left.

Two lutes: one note.
Two flowers: one fragrance.
Two lamps: one light.

Two lips: one word.
Two eyes: one sight.
These two: one universe.

In unity there is little to behold;
So She, the mother of abundance,
Brought forth the world as play.

He takes the role of Witness
Out of love of watching Her.
But when Her appearance is withdrawn,
The role of Witness is abandoned as well.

Through Her,
He assumes the form of the universe;
Without Her,
He is left naked.

If night and day were to approach the Sun,
Both would disappear.
In the same way, their duality would vanish
If their essential Unity were seen.

The book from which these excerpts are taken, is entitled
