This is the meaning (as explained by Solveig and our German friends) beyond the literal translation of the words and reflects more the spirit of the saying:
“Your blessing is with me every day, mornings and evenings, that I happily spread my wings wherever my path may lead me“
Translation (loose translation, as it is written in literary German):
“blessing prevailed (not exactly the right word) over me in every situation (or circumstance), early and late, so that I happily unfold myself wherever my path leads me“
“Prevailed” – more like ‘protects’ or ‘covers’.
