Following a religion strictly and simultaneously following the universal spirituality of all world religions are one and the same concept. I illustrate this by the following example. You have the required medicine for a specific disease in a single bottle. If you strictly take 4ml of the medicine per day from that single bottle only, your illness is completely cured, since the quality of the medicine is same in all the four bottles. 4ml per day from a single bottle or 1ml per day from four bottles stand to be the same in both quality and quantity. Firm belief and strict discipline in using the medicine must exist whether you take the specific quantity of the same medicine from one bottle or from four bottles. You cannot say that a person strictly following the use of medicine from one bottle only, rejecting other bottles, as a blind fool in the sense of curing the illness by using the medicine. When you scold the same medicine in other three bottles, it reflects your foolishness of theoretical ignorance. But, in practical sense, there is no loss if a conservative devotee follows the use of medicine from a single bottle rejecting the other three bottles. Even in the case of a wise man with broad mentality (of universal spirituality) using the same medicine in the same quantity from all the four bottles, the conservative and severe sincerity and firm faith on medicine is the same as that of a conservative blind devotee using the same medicine from a single bottle. As far as the faith on the medicine and the practical usage of specified quantity of medicine is concerned, both universal devotee and conservative devotee are one and the same. Of course, the conservative devotee is not at all blamed in following the use of medicine from a single bottle, but, is blamed for scolding the same medicine in the other three bottles due to ignorance. Instead of scolding, the conservative devotee must be silent about the other bottles and should concentrate on the single bottle about which only he has total faith. You may say that even if the patient scolds other three bottles, the medicine of his selected bottle will not affect in its quality and function. You are perfectly correct, but, you are crossing the limits of simile and applying the concept to the outer restricted area of limits of the simile. Here, the simile is inert medicine and not a living person. This is the limit of the simile and concept is applicable to simile as long as you don’t scold the medicine of other three bottles. The medicine here is compared to God, who is not inert, but has awareness to the extent of infinity based on which we say that God is omniscient. If you praise a person in one dress and scold the same person in other dresses, is he not hurt since he is not like the inert medicine? Since the God in all religions is one and the same, all your praise to God in a specific form of a specific religion goes not only waste, but also, make God to become furious. Hiranyakashipu was a strong devotee of Lord Shiva, but, scolds Lord Vishnu. Both Shiva and Vishnu are different forms or external medium of the same inner unimaginable God. Lord Vishnu appeared as Narasimha and killed the demon. You should note that Lord Shiva did not protect the demon at all! What is the reason? The reason is that Lord Shiva and Lord Vishnu are the same one entity wearing the external media or forms called Shiva and Vishnu. This is the concept between two sub-religions called Shaivism and Vaishnavism in the same Hindu religion. This story is one and the same whether it is in micro-level (sub-religions of Hindu religion) or at macro-level (world religions like Hinduism, Christianity, Islam etc.). The first part of the scripture presents the severe discipline and firm faith in the medicine to be followed by every devotee of each religion. In the second part of universal spirituality, the revered Prophet Mohammed warns every devotee of each religion not to scold forms of God of other religions. Allah is one external form represented by Islam religion. Jehovah is another form of God presented by Christianity. Brahman is another form of God presented by Hinduism and so on. God is one and the same present in all the world religions. You are advised to respect and serve your father sincerely. If possible, realize the fathers of all other people also equal to your father and respect and serve them. If it is not possible, respect and serve your father only and not scold and insult others’ fathers.
