The Talisman could be operated only by certain beings with certain types of minds and something else besides (could it be, he wondered, with certain kinds of souls?). "Sensitives" was the word he had used in his mental translation of the term for these kinds of people, but once again, he could not be sure if the word came close to fitting. The Talisman was placed in the custody of the most capable, or the most efficient, or the most devoted (whichever it might be) of the galactic sensitives, who carried it from star to star in a sort of eternal progression. And on each planet the people came to make personal and individual contact with the spiritual force through the intervention and the agency of the Talisman and its custodian.
He found that he was shivering at the thought of it — the pure ecstasy of reaching out and touching the spirituality that flooded through the galaxy and, undoubtedly, through the universe. The assurance would be there, he thought, the assurance that life had a special place in the great scheme of existence, that one, no matter how small, how feeble, how insignificant, still did count for something in the vast sweep of space and time.
