The Bowl of Saki Commentary

The average person under the influence of ego casts shadow thoughts over the heart so that the heart does not experience bliss. Happiness is not to be confused with momentary pleasure. One way to distinguish them is this: any act, speech, or thought which, while bringing some pleasant result, also affects one at some point in an unpleasant manner—that is to say, the result is alloyed—is not of the nature of happiness. A happy condition is one unalloyed, when there is nothing to mar it, when it is one whole, complete, and consistent experience of joy.

By repeating "Toward the One" it is possible to get one complete effect from every cause. This makes possible later, when a happy result is either desirable or given one by Divine Grace, that it is a pure state unaffected by mental shadows or thought forces. Purification of heart helps more than anything else in this direction.
