There is a practice carried out in Plum Village by Thich Nhat Hanh which is called "The Three Earth Touchings."
It is intended to reconnect us with blood and spiritual ancestors by realizing that we are all interconnected beyond time and space.
As I read it over every day as part of my Insight Meditation, I find that it also makes concepts such as compassion, empathy and dependent origination easier to grasp.
I have copied the link for those who would like to read it whole, but I have transcribed the two that strike me the most:
"I see that this body, made up of the four elements, is not really me and I am not limited by this body.
I am part of a stream of life of spiritual and blood ancestors that for thousands of years has been flowing into the present and flows on for thousands of years into the future.
I am one with my ancestors.
I am one with all people and all species, whether they are peaceful and fearless, or suffering and afraid.
At this very moment, I am present everywhere on this planet.
I am also present in the past and in the future.
The disintegration of this body does not touch me, just as when the plum blossom falls it does not mean the end of the plum tree.
I see myself as a wave on the surface of the ocean.
My nature is the ocean water.
I see myself in all the other waves and see all the other waves in me.
The appearance and disappearance of the form of the wave does not affect the ocean.
My Dharma body and spiritual life are not subject to birth and death.
I see the presence of myself before my body manifested and after my body has disintegrated.
Even in this moment, I see how I exist elsewhere than in this body.
Seventy or eighty years is not my life span.
My life span, like the life span of a leaf or of a Buddha, is limitless.
I have gone beyond the idea that I am a body that is separated in space and time from all other forms of life."
"I am one with the wonderful pattern of life that radiates out in all directions.
I see the close connection between myself and others, how we share happiness and suffering.
I am one with those who were born disabled or who have become disabled because of war, accident, or illness.
I am one with those who are caught in a situation of war or oppression.
I am one with those who find no happiness in family life, who have no roots and no peace of mind, who are hungry for understanding and love, and who are looking for something beautiful, wholesome, and true to embrace and to believe in.
I am someone at the point of death who is very afraid and does not know what is going to happen.
I am a child who lives in a place where there is miserable poverty and disease, whose legs and arms are like sticks and who has no future.
I am also the manufacturer of bombs that are sold to poor countries.
I am the frog swimming in the pond and I am also the snake who needs the body of the frog to nourish its own body.
I am the caterpillar or the ant that the bird is looking for to eat, and I am also the bird that is looking for the caterpillar or the ant.
I am the forest that is being cut down.
I am the rivers and the air that are being polluted, and I am also the person who cuts down the forest and pollutes the rivers and the air.
I see myself in all species, and I see all species in me."
