According to science, water is the most mysterious and least understood substance in the universe. According to Kabbalah, water is the Light of God made manifest in the physical world.

Hence water pollution is both a physical and spiritual crisis.

When the water in our lakes and the water in our cells are tainted with physical and spiritual toxins, our personal and global immune systems are dangerously weakened.

Genuinely pure water has the power to cleanse both physically and spiritually. In the same way that water miraculously dissolves dirt, grime, and filth from the physical body, water's metaphysical essence dissolves away the spiritual uncleanliness and negativity that we've brought upon our body and soul.

The Kabbalists say water can naturally heal, water can rejuvenate, and water holds the secret to immortality. But centuries of war, persecution, and hatred took its toll; thus water lost this intrinsic power.
