Mysticism to the mystic is both science and religion.

Bowl of Saki, by Hazrat Inayat Khan

Commentary by Pir-o-Murshid Inayat Khan:

What we generally know as the breath is that little inhaling and
exhaling which we feel through the nostrils. We think that is breath
and attach little importance to it, while in reality, breath is a
life-current running through the innermost part of man's being
towards the surface. It would be no exaggeration, according to the
mystical point of view, to say that the breath connects heaven and
earth. ...

For the mystic, breath is not only a science, but the knowledge of
breath is mysticism, and mysticism to the thinker is both science and
religion. The mystery of breath is not a thing that can be
comprehended by the brain only. The principles of mysticism rise from
the heart of man. They are learned by intuition and proved by
reason. ...

If we consider the conditions of life today, we see that, however
much man thinks he has progressed, certain aspects of life are
neglected in the way of health, repose, balanced thinking, and in the
way of kindness and love to one another. All these things are
lacking, and the spirit of the present time seems to be going in
quite the opposite direction.

Selfishness seems to be so much on the increase. Real religion, the
spirit of forgiveness, generous giving, regard for old age,
refinement, culture -- all seem to be disappearing. Man in general,
does not know even if there is a God or Truth. If this is the spirit,
how can we expect to find that harmony, peace and love, which make
heaven on earth?

It is useless to discuss the peace of the world. What is necessary
just now is to create peace in ourselves that we, ourselves, become
examples of love, harmony and peace. That is the only way of saving
the world and ourselves.
