A parallel exists between teaching Torah and a commercial venture. An entrepreneur attempts to advance his business by establishing it in a busy location. Then he tries all types of novel ideas to attract the attention of the passers-by. The potential customers may be too preoccupied to notice the store and may pass it day by day without stopping in. However the owner hopes to implant his presence in their mind for the day when they need something, recall the presence of the store, and drop in to make a purchase.

The same principle applies when choosing a venue for the learning of Torah. Classes and study sessions should be held in a location that is visible and accessible to the public. A person who has repeatedly passed through the area without stopping may suddenly find his interest aroused and walk in to see what is being offered. All efforts must be made to publicize classes and encourage others to join.

Also, in keeping with a successful marketing strategy, a good merchant sells no merchandise before its time, but waits until the right moment, when profits will be greater.

So too is it with G-d and the goodness He exhibits towards the creation. Even though it may appear that the good He bestows on us is not forthcoming, it is likely that, within a short time, divine benevolence will prove to be much greater than at first perceived.
