True happiness is synonymous with God and that is eternal, unlimited, infinite, permanent and immeasureable. (Chandogya Upanishad)

Once divine bliss is attained, it is attained forever. (Vedas)

God is bliss (ananda). From bliss all beings are born, in bliss all beings are sustained, and into bliss all beings will merge at the time of complete dissolution of the universe. (Taitariya Upanishad)

God is omniscient (all-knowing). He Himself is the form of knowledge. (Mundak Upanishad, 1/2/9)

He is God, the supreme divine personality who is the governor of Maya (material energy). He is the one in whom the material universe exists and from whom the material universe evolves. Within Him the material universe is established, and due to His inspiration the material universe is produced. (Bhagwatam, 10/18/4)

God does exist, and He can be experienced. When you have complete faith in Him, you receive God's grace fully, and due to this you are liberated from Maya forever. (Vedas)

God is omniscient and omnipotent. The individual soul has limited powers. Due to Maya, he is in ignorance and attached to the sense objects of the world. Both God and the souls are eternal. Apart from these two there is a third eternal existence: Maya. God is supreme. He enlivens Maya through His grace, and with this inspiration, Maya creates this universe. God is not the direct creator of this world. (Vedas)

Krishna says in the Bhagavad Gita, "I am the ultimate goal of the all the souls. I am their protector. I grace them with divine knowledge and love. I am their loving supreme God. I am the observer of the actions of the souls. All the souls reside in Me; I am their ultimate refuge when they humbly surrender to Me." (Bhagavad Gita, 9/18)

God is one. He resides in the hearts of all the living beings. He is omnipresent. He is the supreme soul of all the souls and graciously observes all their actions as an eternal witness. He is absolute bliss, which is beyond all mayic (material) qualities. (Shvetashvatar Upanishad)
