According to the most commonly accepted origin story the six gems were once part of an all-powerful being who committed suicide out of loneliness. Its power survived and manifested as six gems. The Soul Gem was in the possession of the High Evolutionary when he oversaw the rebirth of Adam Warlock. He gifted the gem to Warlock to aid him in his mission to save the world of Counter-Earth. During that time, Warlock primarily used the gem's powers to restore evil New Men to their pre-evolved animal forms.
However, as he had in an earlier scheme to gain ultimate power, Thanos would sow the seeds of his own Destruction. Thanos purposely enraged Adam Warlock, by wiping the mind of Adam's companion Pip, and leaving him to be found. When Warlock found Pip's mindless form, he drew his friend's spirit into his Soul Gem. But before attacking Pip, Thanos had told him of his plan, and drawing Pip's soul into the Gem caused Warlock to learn of the plan.
