' Fundamental Basis of all Religions and Beliefs '...

As water in a fountain flows as one stream, but falls in many drops
divided by time and space, so are the revelations of the one stream
of truth.

Bowl of Saki, by Hazrat Inayat Khan

Commentary by Pir-o-Murshid Inayat Khan:

In a fountain there is a big stream which flows up and then breaks
into many drops. The stream is like the divine will, and the
different drops like the wills in us. One drop goes higher, another
lower, one falls to the left, another to the right, one goes north,
another south. But the source of all this activity is one; it is one
thing that turns into so many, scattering in all directions. Thus
from unity there has come variety.

Different methods called religions and philosophies have been adopted
by different nations at various periods. Though the form and
teachings of the several religions appear so unlike, their source is
one and the same. But from the very beginning the differences have
created prejudice, envy, and antagonism between man. Such dissensions
occupy a large portion of the histories of the world and have become
the most important subject in life.

So many castes and so many creeds,
So many faiths, and so many beliefs,
All have arisen from ignorance of man,
Wise is he who only truth conceives.

A wise man realizes that the fundamental basis of all religions and
beliefs is one: Haqq, or truth. ... Those who see the truth uncovered
abandon reason and logic, good and bad, high and low, new and old;
differences and distinctions of names and forms fade away, and the
whole universe is realized as nothing other than Haqq. Truth in its
realization is one; in its representation it is many, since its
revelations are made under varying conditions of time and space.

As water in a fountain flows in one stream but falls in many drops,
divided by time and space, so are the revelations of the one stream
of truth.
