But soule we finde too earthly to ascend,
105'Till slow accesse hath made it wholy pure,
Able immortall clearnesse to endure.
Who dare aspire this journey with a staine,
Hath waight will force him headlong backe againe.
No more can impure man retaine and move
110In that pure region of a worthy love:
Then earthly substance can unforc'd aspire,
And leave his nature to converse with fire:
