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,
The human form of life is rare and valuable.
Srimad Bhagavatam 2.3.2-7,
Krishna's land is being destroyed by the greed for luxury in Kali Yuga.
In the darkness of night a snake can find its eatables simply by hearing the frog's very pleasant cry. Similarly, people who are taking all nonsense without Krishna Katha, they are inviting the Yamaraj.
