Classic Poem

What's a good conscience, Eccho, canst say? Ay!
Say then, and what 'tis manifest. A feast!
Where is't? i'th' understanding wholly? O lye!
Is it then, Eccho, in my brest? My rest!
Rest? is't from pain or sin, say whether? Either!
If both, 'tis heaven on earth, a saint's bliss. Yes!
Is't in our own or others powers? Ours!
O then a jewel 'tis, rich and bright. Right!
Then tell me how shall I come by it? Buy it .
If gold will buy't gold I'l provide. O wide!
If gold will not, what else will do it? Do it!
It's not enough that I believe well? Live well!
Dos't not consist in good affections? Actions!
To get it are good works the best way? Ay!
How long must this be my endeavour? Ever!
