1,217 --> 218 = Vajra

The vajra, the brass Vajrayana implement, is appropriately connected to the heart via Gematria. Just as "the vajra" = 228 = "beloved + beloved," the physical heart is one sheet of tissue twisted like a Möbius strip into an inner and outer layer, each with fibers running in contrary helical directions. Those familiar with Highest Yoga Tantra will recognize the allegory: two that are one, in a form symbolic of Eternity.
