You ask: Who/what is God?
God is existence –total existence. In fact, existence and God are synonymous. Since existence is God, God exists. God not only exists but God alone exists. To see God as God truly is, one must see God as manifest in every form throughout the universe.
The totality of existence is God. “A God defined is a God confined,” said Swami Rama Tirtha (1873–1906), one of the greatest spiritual masters of India.
God, who is present in all places, at all times, and in all things, must be present in this place, at this time, and in this thing. So, it follows that God is present within each of us. If God is not within, God is nowhere else.
Ask yourself this question: Do you exist or not? Your answer will inevitably be, “Yes.” It is impossible to deny your own existence — it is like a person saying with his own tongue that he has no tongue. You exist, therefore God exists.
To know God exists is not enough. You should experience this God within. For example, the only way a piece of salt could know the sea is by becoming the sea. In Samadhi (union with the Absolute), the last of Patanjali’s eight limbs, God is experienced. Once you experience God within you, you will be able to see God everywhere.
Our great sages have declared that God lives within, so it makes perfect sense to turn within to experience God. Given below are quotes that refer to the true religion of oneness, which if understood rightly by Christians, Jews, Hindus, Muslims, and so on, there will no reason for a religious fight anymore.
“The kingdom of God is within you.” (Luke 17:21)
“I Am That I Am.” (The Old Testament — Exodus 3:14)
“God lives in the heart of every being” (Bhagavad Gita 18-61)
Aham Brahmasmi, “I am the Absolute” (Yajur Veda)
Ana’l-Haqq, “I am the Truth” or “I am God,” said al-Hallaj Mansur (858-922), a famous Sufi saint.
“Having created the physical bodies of all creatures, God Himself entered into them to make them alive and active.” (Taittiriya Upanishad)
The Scientific Proof of God’s Existence
Science now accepts that the entire universe is made up of one energy. Everyone and everything that exists in this universe is energy. Our ancient sages said this energy is One and called it supreme consciousness, absolute reality, or God. Whatever name you call God by, it’s the same God. All religions are of fairly recent origin, but God as energy has existed since the beginning of time. If everybody were to understand and accept this truth, then all differentiating between “our God” and “their God” would vanish.
One of the most basic laws of science —the Law of Conservation of Energy — claims that energy cannot be created or destroyed, but only changed from one form into another. What science claims is nothing but God. Albert Einstein’s famous equation proves that matter can be reconverted into energy. Hence, the matter is another form of energy, just as ice is another form of water. In reality, the same energy manifests as light, heat, electricity, magnetism, and sound, and they are inter-convertible.
The striking conclusion of modern scientists — that energy is the essence of all that exists within the universe – is undeniable. In infinite forms, the same God pervades everywhere.
There was a time, about five hundred years ago during the time of Christopher Columbus (1451 – 1506), when most people believed that the earth is flat, but now science has established that the earth is spherical. In the same way, the idea that God is energy and therefore, existence, is now very convincing from a scientific point of view.
God is love
When it is said in scriptures, “God is love,” it means love is God, not God is loving. Love and God are synonymous. Love can not only be proved, but it can also be experienced. This love is the evidence of God. There is no need to believe in love because you can experience love. Can anyone ever deny that love does not exist?
