भ्रमन्ति च तथाकाशे पक्षियोनिङ्गताःक्वचित् |
जले वसन्ति च तथा झष योनिङ्गताः क्वचित्  ||
एवं बहिविधैर्लोके संभवैर्योगसिद्धयः |

विरक्तस्य सुखं मे किं ह्येवमाश्चर्यचेष्टितैः  ||

Roopalal Said

The varied species are born on this earth again and again as a result of multifarious deeds, if once as mosquitoes, at another as elephants. Sometimes they are born as birds and fly high in the sky. Sometimes they take birth as fish and live in the water. Thus in multitudes of births many yogic powers have been acquired and experienced. But devotion to Shri Krishna has never been acquired. What benefit do I, a dejected saint derive from such yogic accomplishments that excite the laymen alone.
