Is it not better to earn more and sacrifice more for God's work?

[Question by Dr. Sheshadri Thiruvenkadam (Balaji).] 

Swami rerplied: One should not be lazy and one should put his maximum effort in doing any work. But if one earns only a little in spite of his best effort, one need not be discouraged because God looks at the percentage of sacrifice and not the magnitude of the sacrifice. Suppose a person lives in India and earns Rs. 100 and donates Rs. 20 to God. Another person lives in USA and earned $100 and donates $10, which are equal to Rs. 400. Which is the greater sacrifice? The sacrifice of Rs. 20 is greater than the sacrifice of the Rs. 400 because the former is 20 % of the first person’s salary and the latter is only 10 % of the second person’s salary. Dharmaraja sacrificed 3 crores[1] of rupees (just an assumption) to priests during the Ashwamedha sacrifice and as a result, he went up to heaven, which is the 3^rd upper world[2]. Saktuprastha sacrificed flour worth just 3 rupees to the hungry guest during a drought but he sacrificed entirely; that was everything that he possessed. He went to Brahma Loka, which is the 7^th upper world. This concept of God is quite different from say a railway ticket, where the charges are proportional to the distance traveled[3].

[1] 1 crore = 10 million

[2] According to Hinduism, there are 6 worlds above this world (totally seven upper worlds), which are different levels of heavens and seven worlds below it, which are different levels of hell.

[3] Travelling to Brahma Loka, which is farthest away from our world, cost Shaktuprastha only Rs. 3, while traveling to the 3^rd heaven, which is much closer to here, cost Dharmaraja over Rs. 3 crores.
