1. The flaw of materialistic philanthropy

    One who can understand that Krsna is the proprietor of all the three worlds and that He is the friend of everyone is peaceful and independent. As long as a conditioned soul does not have this knowledge, he wants to be the enjoyer of everything; he wants to become a humanitarian or philanthropist and open hospitals and schools for his fellow human beings. This is all illusion, for one cannot benefit anyone by such material activities. If one wishes to benefit his fellow brother, he must awaken his dormant Krsna consciousness.

    From Srila Prabhupada's purport to SB 3.27.25
