For may sorrows arise 'pon departures near, 'Til reflective silence shares its warm relief, Regards to what once hath we deeply cared, Has faithfully faded into the abyss beneath.
Ah, but do bid thanks to the pains that may never rid, And the momentarily bliss that has Past like Gust, For inevitably shall foul shapes fair - as thanks to bid, To draw'st me back to whom I faithfully trust.
A poem on thanking the events that has given us many sorrows but has in turn shaped us into who we are and who we truly trust. Past (Passed) refers to the past and Gust refers to a person. Fair/Foul refers to Macbeth.
