The Sacred word that binds them all

Hinduism and Christianity is poignantly very similar. What is Christ to Christians is Krishna to Hindus. The underlying tenet of both religions stems from metaphysics which preaches that there is one and only God which is in the form of light. The only way Hinduism differs with Christianity is in the path that leads to this Supreme God. Many enlightened souls (Aatma) of past and present, merged into this Supreme Soul (Parmatama) through years of spiritual meditation (not to confuse with New Age Yoga). Take for instance Paramhansa Yoaganand ( Autobiography of a Yogi), an enlightened soul who achieved self realization through years of practicing the teachings of Lord Krishna in Bhagwad Gita known as "Kriya Yoga" (Kriya means Action and Yoga means "the state where you unite with the Divine"). Essentially in a nutshell it means - by constantly doing something good, you are progressing towards divinity. From the spiritually enlightened lenses, "doing something good" is far more than physical action, it is the mental action that you perform within by practicing any spiritual methodology for e.g. locked in a lotus posture you are honing into the Christ consciousness (region between your eyes) or silently chanting "OM" or "AUM" "AMEN" in Christianity, "AMEEN" in Islam that will eventually have far reaching consequences.

Buddhism is an offshoot of Hinduism which is very clearly evident by how Lord Buddha attained spiritual enlightenment. He was born into a Hindu family who left the palatial pleasures in search of God. When he was finally spiritually enlightened, it happened in the form of a blinding light that took all over him and thus he merged into the Supreme.

The essence of Bhagwad Gita and thus Hinduism is, "Know thyself (yourself) by performing Karma or Kriya" which in this case is spiritual meditation and you will know God. No one religion is better or worse than other, if one religion can take you to God, it is the best for you. Ultimately what matters is attaining that state of spiritual enlightenment or self-realization, without which you will never reach God.

As for drawing parallels among the three religions we are talking about, the single most powerful thread that binds them all is in the commonality of the the sacred word across these religions AUM for Hindus, Amen for Christians and Ameen for Muslims. This is the sacred word from where the universe is believed to be originated. "In the beginning was the Word, and the Word was with God, and the Word was God. (John 1:1 KJV)".
