Fruits of Solitude (1682), Part I
Context: Love is indeed Heaven upon Earth; since Heaven above would not be Heaven without it: For where there is not Love; there is Fear: But perfect Love casts out Fear. And yet we naturally fear most to offend what we most Love. What we Love, we'll Hear; what we Love, we'll Trust; and what we Love, we'll serve, ay, and suffer for too. If you love me says our Blessed Redeemer) keep my Commandments. Why? Why then he'll Love us; then we shall be his Friends; then he'll send us the Comforter; then whatsover we ask, we shall receive; and then where he is we shall be also, and that for ever. Behold the Fruits of Love; the Power, Vertue, Benefit and Beauty of Love! Love is above all; and when it prevails in us all, we shall all be Lovely, and in Love with God and one with another.

Upon the Sovereign Sun (362)
Context: One indeed is the Creator of all things, but many are the creative powers revolving in the heavens; we must, therefore, place the influence of the Sun as intermediate with respect to each single operation affecting the earth. Moreover, the principle productive of Life is vastly superabundant in the Intelligible World; our world, also, is evidently full of generative life. It is therefore clear that the life-producing power of the sovereign Sun is intermediate between these two, since the phenomena of Nature bear testimony to the fact; for some kinds of things the Sun brings to perfection, others of them he brings to pass, others he regulates, others he excites, and there exists nothing that, without the creative influence of the Sun, comes to light and is born.
