You have fully delineated the subject of impersonal Brahman as well as the knowledge derived therefrom. Why should you be despondent in spite of all this, thinking that you are undone, my dear prabhu?
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
जिज्ञासितमधीतं च यत्तद्ब्रह्म सनातनम् । अथापि शोचस्यात्मानमकृतार्थ इव प्रभो
jijñāsitamadhītaṃ ca yattadbrahma sanātanam | athāpi śocasyātmānamakṛtārtha iva prabho
