For in spite of all our intention, all our creed, all our purity, all our desire and all our will, once we arouse the dynamic relation in the upper, higher plane of love, we inevitably evoke a dynamic consciousness on the lower, deeper plane of sensual love.

And then what?
Of course, parents can reply that their love, however intense, is pure, and has absolutely no sensual element.

Maybe--and maybe not.

But admit that it is so.

It does not help.
