Very often birds and animals give warning of death in the family. One might think that they know from somewhere, or that they have a mind that thinks about it. The condition is reflected upon them. The condition of the person who is dying, the thought of those who are around him, the condition of the cosmos at that time, the whole environment, everything there is reflected on their mind. And they know, they begin to express their feeling, and they become a warning of the coming death.
