A person must always do just one thing; they cannot do everything at once. It must always be one thing, and within it, everything else must be understood. If a person wants to do this and that, everything at once, and departs from their own path to appropriate someone else's path, which seems more appealing to them, it causes great instability… Let a person accept a good path as their own and remain on it forever, but it is important that this path is accepted from God. Let them not strive for one thing today and another tomorrow, and above all, let them not worry that they will miss something because of it. With God, a person cannot miss anything. God cannot miss anything, and therefore nothing can be missed with Him. Therefore, accept one path from God and "pull into" it everything that is good.
