Context: Generally speaking, the significance of the indirect results may very often be of more importance than the significance of direct ones. And since we are able to trace how the energy of love transforms itself into instincts, ideas, creative forces on different planes of life; into symbols of art, song, music, poetry; so can we easily imagine how the same energy may transform itself into a higher order of intuition, into a higher consciousness which will reveal to us a marvelous and mysterious world.

It must not be just a fleeting moment but a physical bond between the varying events in life. Not extractions, but abstractions. Abstractions that are like nothing in life except in their manner of reacting.
