Talmud Five is the number of regeneration. Form is ripe and ready in three-dimensional space, and now it is time for this form to recreate itself. The Pentad is present everywhere. The human body expresses the Pentad's symmetry in its five senses, five extensions from the torso with each limb ending in five fingers or toes. Pentagrams are stars we see fluently in advertising and corporate logos.
Most flags embody a five-pointed star somewhere in their symbolism.
Cut open an apple and you will notice that the core is in the shape of a star. The Pentad is also the key to the self-generating number series knows as the Fibonacci sequence. The series is a self-accumulating sequence that grows from within itself, it's immediate past and takes nothing from outside the sequence for additional growth. This is the essence to the Pentad's principle of regeneration, self-replicating growth, which began from nothing and became everything. Sacred geometry is the study of how the universe was constructed through number and form.
