All four stanzas are beautifully crafted as usual, but the second, in my opinion, is wonderful. Such beautiful imagery conjured there. Wonderful, original write.

Love it! I am huge on science and the universe, psychics and everything above so this first stanza really grabbed me. The words and your vocabulary that you used is so broad it's always great to see poets broaden their vocab.

Once, twice, thrice - a phrase as old as time, yet as new as dew on a dragonfly's drying wing.
Words infused with intense emotion and tenderness.

Beautifully finished, I relate this as the phrase being "I love you" because love is as old as time as it is the strongest vibration within the entire universe and even as old as they are whenever one truly says them and means then they are new, intense, and full of tender.
