There is a certain power of protection in receiving blessings from good people. Those blessings have a special potency as they are coming from spiritually evolved people.
Krishna does many things, if you want something constructive and something useful he wiil give it to you but then he will also see whether you are ready for it . So it takes time sometimes to get the blessings of Krishna, it doesn't come when we want it, they come when we are ready for it.
The real blessing we can get from Srila Prabhupada is if we read his books.
