“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. He can be served simply by hearing, He can be served simply by chanting or reading about His activities, He can be served simply by adoring Him and accepting Him.” (Shrila Prabhupada, Shrimad Bhagavatam, 2.9.36 Purport)
