I believe there is no death, only other realms that we go on to after life on Earth. When a soul no longer has to return for more lessons on Earth, then there is the opportunity to become helpers/guides for other souls on earth. The soul will continue to learn and spiritually grow in other realms.
It takes many, many life times for a soul to reach the level where living another life on Earth is for guidance of others.
Walk in Peace and Harmony.
