Why is there a contradiction between the philosophies of Shankara, Ramanuja and Madhva?

The commentaries of the three Acharayas [Shankara, Ramnuja and Madhva] are different, but do not contradict each other. Only the disciples of the Acharayas are contradicting each other, because they have not taken the correct version of the commentaries. The disciples misunderstand the commentaries. The correct version of the commentary can be seen from the practical life of their Acharya, because each Acharya definitely knew the correct version of His own commentary and must have practiced it. If you see the life of Shankara, He left His mother and traveled all over India. The entire world became His family. He could have earned a lot of money by visiting any king [but he did not]. This shows that He had cut all the bonds with His family and money. He did not sit idle. He propagated the divine knowledge and worked day and night for that. He worked for the upliftment of all people. He swallowed molted lead and preached to His disciples that He alone is the Lord in human form. One may get confused in a theory class, but one will have the clear concept from the practical class in a laboratory. Therefore, observe what the Acharya practiced, you will get the correct version of His commentary. Shankara gave the knowledge of the self, which is pure awareness. This awareness is Brahman. Therefore your self is the Brahman and not your body. By this you get peace because all the bonds with the body and the family are removed. This is an intermediate stage. Shankara preached this stage to all the people.

The final stage is reaching Ishwara, who is in the human form. Shankara, Himself was the Lord in human form. He preached this to a few deserving disciples by swallowing molted lead. After Shankara, Ramunaja came, who was Shankara Himself in a new body. He showed the final goal which is Ishwara as Lord Vishnu, who is not before your eyes. You will not believe Lord Krishna in human form, who is before your eyes, due to your jealousy. At last Madhva came and introduced Hanuman, who is the servant of the Lord in human form (Rama). He claimed Himself to be the younger brother of Hanuman. That means, as the younger brother serves the elder brother, first you must serve the servant of the Lord before you become a direct servant of the Lord. Thus the three Acharyas came in the correct sequence of time showing the correct sequence of the steps in the spiritual path.
