THE PLANETS
The Seven double letters are Bet, Gimel, Daled, Kaf, Peh, Resh, and Tav. Defined as double since they have two sounds hard and soft (the aspirated and the softened) associated with each of them.
They are also called double letters because they signify the contraries in the universe: Life, Peace, Wisdom, Wealth, Gracefulness, Prosperity, Power and their opposing forces.
The Seven Double Letters produced the 7 planets, the 7 days of the week, and the 7 Gates of the Soul (our orifices of perception).
