A Vedantic Perspective
The fundamental truth as taught by all religions is that man has to transform his base human nature into the divine that is within him. In other words, he must reach the deeper strata of his being, wherein lies his unity with all mankind. And Vedanta can help us to contact and live that truth which unfolds our real nature ó the divinity lying hidden in man.
Vedanta is not a particular religion but a philosophy which includes the basic truths of all religions. It teaches that manís real nature is divine; that it is the aim of manís life on earth to unfold and manifest the hidden Godhead within him; and that truth is universal...
Thus Vedanta preaches a universal message, the message of harmony. In its insistence on personal experience of the truth of God, on the divinity of man, and the universality of truth it has kept the spirit of religion alive since the age of the Vedas (ancient scriptures). Even in our time there have been Ramakrishna, Vivekananda, and men like Gandhi...
This "sum total" of all religions does not mean that all people on earth have to come under the banner of one prophet or worship one aspect of God. If Christ is true, Krishna and Buddha are also true. Let there be many teachers, many scriptures; let there be churches, temples, and synagogues. Every religion is a path to reach the same goal. When the goal is reached the Christian, the Jew, the Sufi, the Hindu, and the Buddhist realize that each has worshiped the same Reality. One who has attained this knowledge is no longer a follower of a particular path or a particular religion. He has become a man of God and a blessing to mankind.
