When there is no darkness, then there is neither day nor night, neither being nor non-being — only the gracious One alone. That is the imperishable, that is the adorable light of Savitṛ, and from it flowed forth the ancient wisdom.
यदाऽतमस्तान्न दिवा न रात्रिः न सन्नचासच्छिव एव केवलः । तदक्षरं तत् सवितुर्वरेण्यं प्रज्ञा च तस्मात् प्रसृता पुराणी ॥ १८॥
We have been given this human life to understand the all-pervading, omnipresent God. This knowledge can only be given by someone who has themselves realized God. Life becomes truly happy only after meeting such a God-realized person.
God is the enduring one, and everything else is transient.
No one can come unto Me, except the Father which hath sent Me draw him.
