Yet, science has documented enhanced crop growth with use of his shape installations; significant improvements have been demonstrated.
Dr. Karim believes that everything is energetic. The energy inside of a body or a shape - even a 2D shape - vibrates. Since the energy is confined to the shape, the energy bounces off the boundaries and wave interference patterns can result. Special shapes produce powerful interference patterns - these become the shape's signature energy.
Sigils were also used in the Kabballah Tree of Life. Each sephiroth (a circle on the Tree of Life) contains a written symbol from the ancient Hebrew language. Most Ancient languages were not symbolic as languages are today but were based on the literal meanings of the sounds of the words. It is analogous (roughly) to what is called onomatopoeia in English today.
These are words that resemble the sound that they describe, like oink, meow, roar and chirp. In another example, bees buzz. Both of these words have literal vibratory meaning - a child would understand. Ancient languages made extensive use of encoded-sound-vibrations; these languages contained beneficial sounds in many syllables and words.
In the case of the sephiroths each symbol was believed to be a gateway to the energy of an attribute of God. As mankind involved into matter, we lost the higher octaves and vibrations of God.
We became a "Shadow of God" or "Children of God", that entered duality, experiencing positive and negative energies. We felt separated from the wonderful all-encompassing energies of God. Kabballah disciples intently viewed the sephiroth symbols for literally many hours to receive emanations of divine energy. The sephiroth symbols were a "portal" to the energies of God.
Many ancient traditions revere the "sounding of the names of God". Each name represents the energy of an aspect of God that we hope to acquire in this lifetime... such as mercy, forgiveness or kindness. This deeply spiritual practice of reciting the names of God is professed to be transforming.
