God was aware that he can't reach easily everywhere and every place all the time (not because it is not possible by him - But he was aware that probably Human Being will not trust that - " How come GOD is every where and every place all the time - Because Human being will feel less importance for himself as well as for GOD. This is also because he can't massage his EGO too, that GOD comes only at our place/house etc.), So GOD came out with best idea, he gave MOTHER in every home, who will work on his behalf and give all love and take care of all family members. She will be guide and teacher too. Shri. Rabindranath Thakur Said that People will trust and believe every one that he is such a famous and big personality, but his family members and neighbors will never believe that famous personality, because they have seen them since childhood and his all activities - good and bad. They can't see his good or major side of it, but they will always fall back on lower side. So GOD as given one more substitute of Mother, hence we have so many saints /Paygambar/ masiha / messenger, who are working on behalf of GOD (like GOD / Mother they were also sacrificing entire life for societies upliftment and betterment with out any self motive). But most of us are either believed them when they passed away (not when they were alive) - some are still unfortunate by not trusting them even now. They some times shown ways of life to Human kind by walk the talk / preaches / Books / Messages.
The life of a great saint is itself a miracle. These miraculous works of Saints are not like magic or jugglery. Magic and Jugglery is temporary in nature. The miraculous works of incarnated saints are exceptionally great. These miraculous works transmit permanent influence and wherever it reaches, those locations are beyond the reach of magic or jugglery. Such miraculous works are always in the public interest and philanthropic in nature. All great saints, during his lifetime has performed numerous miracles, sometimes for the mental pleasure and sometimes in the favour of the devotees. The primary aim of their miracles was to eliminate the sufferings of his devotees and to make them happy as well. A magician performs miraculous jugglery and gives deception to the public but great saints by their exceptional miraculous works makes one bow their head.
