Virgo 17. A scientist discovers the secret of time travel.
It is not a machine that one needs so as to move at will through time, but only a realization. When we came here we promised to obey certain rules, one of them being that we would all move through time at the same time together – in a polite and orderly fashion. To break such a promise is well nigh impossible for most, for it would inevitably give rise to unendurable horror and guilt, that is, if one were to do it before moving through the doors of death first.
Actually, all this observation of protocol and strictness in adhering to rules is unnecessary, if one can simply do it in a silent, graceful manner, and preferably rather sharply, like a needle moving through a tapestry.
