The pigeon was used as a messenger, to carry a message from one place to another, and therefore the symbol of the dove is a natural one to represent the Messenger from above. Spiritual bliss is such an experience that if a bird or an animal were to have it, it would never return to its own kind. But it is a credit due to man that after touching that point of great happiness and bliss, he comes into the world of sorrows and disappointments and delivers his message. This quality can be seen in the pigeon also; when the pigeon is sent it goes, but it comes back faithfully to the master who sent it. The spiritual man performs this duty doubly: He reaches higher than the human plane, touches the divine plane, and brings the message from the divine to the human plane.
