Krishna-Dwaipayana Vyasa

 "The wise know that living by scriptural injunctions (good deeds, sacrifice, and so forth) will help you reach heaven. But the true yogi knows that even heaven is part of nature (prakriti) and thus is eventually perishable. This yogi therefore transcends all of nature to reach Me, Brahman, the Imperishable Godhead, the Divine Love who lives in your heart.”
