Bits and pieces on evolution, life and death, personal and universal conscience,... in literature of all ages and places

Just 3 pieces of poetry I've (re)read this afternoon. Enjoy.

"...'Tis all a Chequer-board of Nights and Days
Where Destiny with Men for Pieces plays:
Hither and thither moves, and mates, and slays,
And one by one back in the Closet lays..."

From a poem in the 'Rubaiyat' collection of verses, attributed to Omar Khayyam (Persian mathematician, philosopher, astronomer, ca. 1048-1122) – English translation by Edward Fitzgerald

“...Our revels now are ended. These our actors,
As I foretold you, were all spirits, and
Are melted into air, into thin air:
And, like the baseless fabric of this vision,
The cloud-capp'd towers, the gorgeous palaces,
The solemn temples, the great globe itself,
Yea, all which it inherit, shall dissolve,
And, like this insubstantial pageant faded,
Leave not a rack behind. We are such stuff
As dreams are made on; and our little life
Is rounded with a sleep...”

From 'The Tempest' by William Shakespeare

“Two birds living together, each the friend of the other, perch upon the same tree. Of these two, one eats the sweet fruit of the tree, but the other simply looks on without eating.”

From the 'Mundaka Upanishad', third mundaka, first khanda, mantra n°1
