There is an endless net of threads throughout the universe. The horizontal threads are in space. The vertical threads are in time. At every crossing of the threads, there is an individual, and every individual is a crystal bead. And every crystal bead reflects not only the light from every other crystal in the net, but also every other reflection throughout the entire universe.
Rig Veda

The four tasks a dying person faces also define the four dimensions of care for the dying person: physical, psychological, social, and spiritual.
