'Tis a secret: none knows how it comes, how it goes: But the name of the secret is Love!

… it is that such of us as have loved deeply have learnt many secrets that are unknown to others; for thousands and thousands of things quiver in silence on the lips of true friendship and love, that are not to be found in the silence of other lips, to which friendship and love are unknown. …

You see, a secret is not something untold. It’s something which can’t be told.

Where love is, no disguise can hide it for long; where it is not, none can simulate it

All the secrets of the world worth knowing are hiding in plain sight.

There was after all no mystery in the end of love, no mystery but the mystery of love itself, which was large certainly but as real as grass, as natural and unaccountable as bloom and branch and their growth.

Love is deep, a mystery - who wants to understand its every particular?

Not a secret. It’s very open.

Love cannot be explained, yet it explains all.

Love is an endless mystery, because there is no reasonable cause that could explain it.

The mystery of love is greater than the mystery of death.

He found that love is never to be defined, that it grows and changes with every year of life, that each person knows it as a different miracle... Nothing can shame it. Nothing can make it more splendid than it already is. Shared, wantoned or hidden forever, it can fill a life. There is no understanding love, and there is no defeat so precious as trying. No aspect of life is more complex, and none so simple. A look, a word, and the heart is torn forever; a touch, and it is mended. Love is brave and cowardly. In the same person it is secret and garrulous. But above all, love establishes its own rules and no man can know its complete manifestation in the heart of another.

I can't imagine why knowledge, truth and love should be so much of a secret

The world never knows, and cannot for the life of it imagine, what this man sees in that maid and that maid in this man. The world cannot think why they fell in love with each other. But they have their reason, their beautiful secret, that never gets told to more than one person; and what they see in each other is what they show to each other; and it is the truth. Only they kept it hidden in their hearts until the time came. And though you and I may never know why this lane is called Shelley's, to us both it will always be the greenest lane in Sussex, because it leads to the special secret I spoke of.
