He who dwells in Eternity, saves his time.
Don Juan said that one of the main differences between a sorcerer and an ordinary person is that an ordinary person lives as if he were immortal. He squanders time as if time were his infinite resource.
The sorcerer knows that his time on this Earth is limited. Therefore, he spends every moment of his life effectively.The sorcerer interacts with the Force. The Force comes from the Spirit. The Spirit dwells in Eternity. Therefore, the sorcerer dwells in Eternity.
It is Eternity that reminds the sorcerer that he is powerful, but there is very little time to embody everything that the Spirit points to. There is no time at all for recklessness and stupidity.
