Nonetheless, there is much pure and beautiful love on Earth. Since humans at large are disconnected from the spirit world, their love is very material - it funnels into their loved ones - lovers, children, parents, relatives, friends, pets, god, country and more. Often you will find examples of beautiful and clear love on Earth. Love is also expressed in all forms of art. Much of our art is about love. Art is a purified love essence.
Love of self is not popular in mainstream culture. It is considered a sin. The New Age culture brings back to humans the understanding of The All and puts the love of self in the proper place.
Humans express love in many ways. Many of these ways we share with our animals (that is: human and animal expressions of love are similar). We hug our lovers, touch, kiss, pet, and more. Speaking kindly is a great expression of love. Listening with loving attention is a great expression of love. Feeding and cooking is an expression of love. Sharing a meal, sharing a bed, sharing many activities can be an expression of love. Watching a sunset is an expression of love. Singing, dancing and poetry are expressions of love. Many humans don't realize it but just feeling love inside, focusing on your lover is an expression of love. And, of course, sex can be an expression of love as well.
Humans, in general, are very confused about sex. Modern culture and religion somehow separated sex from reproduction and made it either a sin or a source of pleasure. Nonetheless, the essence of sexual love and sex is the desire to have children and the love for future children.
Even atheists feel love. They assign it to the misregulation of neurons in the brain and hormonal fluctuations. Since their life is focused on survival, they use their love to get pleasure or to procreate. Procreation for the people who don't believe in life after death is a means to extend their life into children.
The fear of many people that there is no life after death makes them anxious to leave a trace in history, to create, to reproduce, and to pass their life experiences to children. Writing memoirs is one of the expressions of this fear.
SELF-SACRIFICE Self-sacrificing love is one of the highest expressions of humans, especially for the ones who don't believe in life after death. Even atheists are capable of self-sacrifice for the good of their group, their country and humanity as a whole.
