The Lord can be served by any ingredient, even the most common commodity — a flower, a leaf, a fruit or a little water, which are available in any part of the universe and without cost and thus the Lord is served universally by the universal entities.
Srimad Bhagavatam 2.9.36,
A pure devotee has no demand from the Lord. His only concern is to serve the Lord sincerely and seriously and he is not at all concerned about what will happen in the future. — Srimad Bhagavatam, 04.09.29.
