Anything of which you are cognizant has a relative vibration within yourself. One who is quick to see and judge evil in other persons has the seed of that evil within himself. The God-like person of pure and high vibrational tone is always aware of the Godspark in all he contacts, and his magnetic soul vibration draws to greater intensity that vibrational force in those who come within his vibrational range.
