In the Vedānta-sūtra, the summarized philosophy of Vedic knowledge, it is said, ānandamayo 'bhyāsāt: "The spirit soul by nature is jubilant." So the Supreme Personality of Godhead, He is supreme living being, and we are also living being, but we are not the Supreme. Try to find out this difference. But both of us, we are of the same quality. That means jubilant. So our present position being materially contacted . . . just like a man in his healthy condition, he is happy, but in his diseased condition he is not happy, similarly, we, being part and parcel of the Supreme, we are naturally jubilant, but on account of being contacted in material nature, we are morose.
In the Upaniṣads, the Vedas, it is said that nityo nityānāṁ cetanaś cetanānām (Kaṭha Upaniṣad 2.2.13): "The God is the chief of the living being. He is the chief of the persons. He is the chief of knowledge." In this way He is described. Just like we can find out amongst us, one is more intelligent, more in knowledge. In this way you search out. God means the most intelligent, the full of knowledge, full of opulence, everything full.
