Water.

The water of Aquarius [an air (mind) sign] relates to our concepts.
Concepts are either true or false.

Satan is a concept that was invented to explain why bad things happen to good people.
Satan is a false concept.

Rewards and punishments (from God) for good or bad behavior are concepts invented by man to satisfy his concept of natural justice.
Rewards and punishments from God are false concepts.

Unconditional love is a concept that we intuitively attribute to God.
Unconditional love from God is a true concept.

We live our lives according to our concepts, but not all our concepts are true.

Judgment and hell are concepts attributes to God after death.
These are false concepts.

We live in fear of things that are not there.
This is darkness.

The light that comes from God dispels the darkness.
No longer will we live in fear.

Darkness hides things (lies).
Light reveals things (the truth).

Aquarian minds enter a meditative state which is like a reverie.  In this state we intuitively answer the big questions.

It is cool rather than hot.
It is clear (like crystal).
it is transpersonal.
It is mutual.

John Bodycomb called it, "A great stream of thought, spreading like flood waters across a plain, reaching into every corner as it goes."

It will touch everyone and everything.
It flows - like a stream of consciousness.
Water flows around and over things and levels out like a spirit level.
Everything is equal.

Concepts like non-violence, truthfulness, gentleness, goodness, self-discipline, charity, even-handednesss, and love surround the divine.

But the key is Love.

Love God and love your neighbor, who is God.
