“My heart skipped a beat and then flat-out tripped over itself and fell on its face. Then my heart stood up, brushed itself off, took a deep breath and announced: "I want a spiritual teacher.”

Context: Now I know surely and forever,
However much I have blotted our
Waking love, its memory is still
there. And I know the web, the net,
The blind and crippled bird. For then, for
One brief instant it was not blind, nor
Trapped, not crippled. For one heart beat the
Heart was free and moved itself. O love,
I who am lost and damned with words,
Whose words are a business and an art,
I have no words. These words, this poem, this
Is all confusion and ignorance.
But I know that coached by your sweet heart,
My heart beat one free beat and sent
Through all my flesh the blood of truth.

Context: I have neither a fear, nor a presentiment, nor a hope of death. Why should I? With my hard constitution, and temperate mode of living, and unperilous occupations, I ought to, and probably shall remain above ground, till there is scarcely a black hair on my head. And yet I cannot continue in this condition! I have to remind myself to breathe — almost to remind my heart to beat! And it is like bending back a stiff spring — it is by compulsion that I do the slightest act, not prompted by one thought; and by compulsion that I notice anything alive or dead, which is not associated with one universal idea. I have a single wish, and my whole being and faculties are yearning to attain it. They have yearned towards it so long and so unwaveringly, that I’m convinced it will be reached — and soon — because it has devoured my existence. I am swallowed up in the anticipation of its fulfilment. My confessions have not relieved me — but they may account for some otherwise unaccountable phases of humour which I show. Oh, God! It's a long fight, I wish it were over!
