The numerical value of bet is two, representing duality. Since it is the beginning of the word berachah (“blessing”) through which every food and drink is reconnected to its heavenly root, bet is also a link between the material world and the spiritual world of unity, reinforcing the truth that God is One.
Blessings open up our awareness of the bounty we receive and thereby open us up for receiving even more. As we stated earlier, the word ברכה – berachah (“blessing”) also means ברכה – bereichah (“large receptacle”). The more we bless God for the good we have received, the larger is the space we make that only He can fill.
Although we experience duality in this world—light and darkness, Yin and Yang, feminine and masculine, etc.—our spiritual work is to reach beyond the duality and reveal the source of Oneness hiding behind all duality. For example, our ultimate capacity for balancing Yin and Yang requires us to tap into pure essence, the deepest place in our souls that is beyond all time, space, and categories. As we shift our identity to pure essence, we may heal from all imbalances and fragmentation.
While Abraham is associated with the energy of alef, which unifies plurality, Isaac, in contrast, evokes the theme of bet, the perception of the deceptive plurality of creation and the need to overcome this deception. Although God’s creation is made of infinite variety and diversity, everything is endowed with His Spirit. Every event and situation is a manifestation of His will, even those which are most enigmatic.
