Pouring down our spiritual highs

Each Korban was brought together with Nesachim of wine. The wine would be poured down one of two holes which were built into the South-Western corner of the Mizbeach. The wine would flow down through the Altar and collect in the Shittin beneath the Temple floor.

Korbanos, like the rising flames of the Altar, are about spiritual elevation. The fire rises upwards, elevating the sacrifice and arousing lofty G-dly energies. But these energies remain beyond, aroused in potential but hidden in the spiritual worlds.
 
Wine, which is drawn from inside of the grape, has the ability to reveal that which is hidden. Our sages teach that when wine enters, secrets emerge.
 
Pouring the Nesachim draws the energies aroused by the Korban downwards, bringing them from their hidden state all the way down into the lowest dimensions of our world.
 
Today, our prayers replace the Korbanos. Our daily davening provide us with an outer-worldly spiritual experience and upliftment. But we need to bring it down to impact the world and help us grow in our daily reality.
The Nesachim reminds us that whilst we need the elevation experience, Hashem’s ultimate desire is that we reveal His presence within the physical world and pour down this connection into the lowest and most mundane aspects of our lives.
