Nichiren Daishonin states in “The Bodies and Minds of Ordinary Beings”:
One who presented a simple meal of millet to the Pratyekabuddha became the Universal Brightness Buddha (Fumyo nyorai). One who offered a mud pie to the Buddha became the sovereign of Jambudvipa. Even if a person performs good deeds, if these deeds are offered to that which is not true, they may bring forth great evil, but they will never produce any good effect. However, even if a person is unintelligent in mind and presents only paltry offerings, if he extends them to an individual who embraces the truth, he will receive tremendous merits. How much more so would be the merit of those who make sincere offerings to the true Law?!

宗祖日莲大圣人于《众生身心御书》曰:
供养稗饭予辟支佛之人，成普明如来。供养土饼予佛者，则成阎浮提之王也。纵行功，若供养非实之事，即成大恶亦不为善。纵心愚物少，若供养真实之人，其功大也。何况以有志之心供养真实之法者乎。
