Shabistari says

What are "I" and "You"?
Just lattices
In the niches of a lamp
Through which the One Light radiates.

"I" and "You" are the veil
Between heaven and earth;
Lift this veil and you will see
How all sects and religions are one.

Lift this veil and you will ask --
When "I" and "You" do not exist
What is mosque?
What is synagogue?
What is fire temple?
