In material consciousness we are trying to love that which is not at all lovable. We give our love to cats and dogs, running the risk that at the time of death we may think of them and consequently take birth in a family of cats or dogs. Our consciousness at the time of death determines our next life. That is one reason why the Vedic scriptures stress the chastity of women: If a woman is very much attached to her husband, at the time of death she will think of him, and in the next life she will be promoted to a man's body. Generally a man's life is better than a woman's because a man usually has better facilities for understanding the spiritual science.
