Have you heard about the dangers of dihydrogen monoxide?  Here are just some of the insidious effects of DHMO.
Death due to accidental inhalation of DHMO, even in small quantities.
Prolonged exposure to solid DHMO causes severe tissue damage.
DHMO is a major component of acid rain.
Gaseous DHMO can cause severe burns.
Contributes to soil erosion.
Given to vicious dogs involved in recent deadly attacks.
Of course, dihydrogen monoxide is none other than two hydrogen atoms bonded to a single atom of oxygen, better known as H2O.  Dihydrogen Monoxide is water.  (See more about the dihydrogen monoxide hoax.)

All year round in the Holy Temple in Jerusalem, the priests would pour libation offerings of wine upon the alter.  On Sukkos, however, there was the special "water libation" in which simple water was offered before G-d.

The drawing of the water on Sukkos was the cause for much joy.  As the Talmud declares, "One who has not experienced the joy of the water drawing festival has never experienced true joy in his life."

What was the big to-do about this unusual offering?

Chasidus explains that there are two kinds of spiritual experiences.  One is likened to wine for it appeals to our senses and arouses our hearts and minds even to the point of intoxication.  The other kind of spiritual experience is much more plain.  Like water, it is life-sustaining but lacks any special taste or appeal. 

A wine-like spiritual experience is typfied by the rousing stimulation of deep meditation, fervent prayer or focussed study, whereas the spiritual experience that is like water is far more subtle.  It is the simple, tasteless experience of surrender -- when one submits to the will of G-d without any particular feeling or understanding.

So again, what is the cause for such joy in simple surrender?

The answer lies in the difference between wine and water.  Ask a thirsty man in the desert which drink he prefers.  The sophisticate and the deep thinker are like the vinophile with discerning pallate.  They are unmoved by water.  They hardly notice it.  They see thier drink as a sensorial experience.  But the simple Jew knows the pleasure of plain water.  He knows the bliss of receiving pure life even when it does not stir the senses.  For in his tasteless, colorless, odorless drink is the greatest pleasure one can experience -- the pleasure of life itself.
