Lord in human form will not allow all people to come to Him, what is the meaning of that?
Generally incarnation of God is not interested in masses. Generally people are in wrong route only. They want to exploit God for their personal solution. They are not coming to learn the real spiritual knowledge and serve God without any aspiration.
Like that no body comes to God. If the human incarnation encourage that wrong route so that several people come to Him then he must not be human incarnation because God in human form does not found of fame masses. He is not found of fame. God is really in that human body, He has already enjoyed lot fame. Will he found of masses and fame? No. He wants to guide the correct people in the correct path. For that purpose He comes not just to attract, get the fame. If such effort is done surely he is not God. He is only a soul is because the soul will always found of fame. He has not tasted the fame already. But God has tasted enough fame. So, any action of God will not be towards the fame. His action will be only to guide correctly the people in the correct path. When His concentration is like that generally masses will not be around Him. Rama and Krishna were not mass personality, also Sankara. Sankara was never drew masses, He was only debating with scholars.
So it is not a question of mass attraction, it is question of leading the people in true path. When He concentrates in leading the people in true path generally people will not like Him. Generally there will not be masses generally there will not be fame. But God is not perturbed. Because He has enough fame, in fact He was bored with the fame. So His tendency will not be towards fame and attraction of mass, His tendency will be always only to give the correct guidance. So in that case generally, the real incarnation of God, He will not be after fame. So that is why the incarnation of Datta means Guru Datta, Guru means preacher. Preacher always sticks to the truth. If He sticks to the truth the people will be less. He does not bother Him because He already God He is not found of fame, He is not politician who draw or attract the masses. So that is what it means.
