So go on with your organisation for distribution of my books through press and other modern media and Krishna will certainly be pleased upon you. we can use everything Television, radio, movies or whatever there may be to tell about Krishna and outside of devotional service all these modern paraphenalia are just so much rubbish.
Giving wealth in service of the Lord, your profits will always increase. Thus you save yourself from repeated birth and death.
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.
Prabhupada is most grateful when we render service to Krishna sincerely and it is by His mercy that we will be able to go back to the spiritual sky.
