At any rate, it is intense enough.

It looks back on the love he has lost, on passion with the woman he loved.
And he would surrender all--Heaven, Nature, Man, Art--in this momentary fire of desire; for indeed such passion is momentary.

Momentariness is the essence of the poem.

"Even in heaven I will cry for the wild hours now gone by--Give me back the Earth and Thyself." _Speculative_, he calls it, in an after irony.
Others may need new life in Heaven-- Man, Nature, Art--made new, assume! Man with new mind old sense to leaven, Nature--new light to clear old gloom, Art that breaks bounds, gets soaring-room.
I shall pray: "Fugitive as precious-- Minutes which passed,--return, remain! Let earth's old life once more enmesh us, You with old pleasure, me--old pain, So we but meet nor part again!" Nor was this reversion to the passion of youthful love altogether a new departure.

The lyrics in _Ferishtah's Fancies_ are written to represent, from the side of emotion, the intellectual and ethical ideas worked out in the poems.
