पूर्वेभ्यस्तु प्रयत्नेभ्यो विषमोऽयं हि संस्मृतः ।
दुःसाध्यो वासनात्यागः सुमेरून्मूलनादपि ॥ १० ॥

saṃsmṛtaḥ duḥsādhyaḥ vāsanātyāgaḥ sumerūnmūlanāt api

saṃsmṛtaḥ vāsanātyāgaḥ sumerūnmūlanāt api duḥsādhyaḥ

10. This (abandonment of vāsanā) is indeed considered more difficult than any previous efforts. The renunciation of latent impressions (vāsanā) is harder to accomplish than even uprooting Mount Sumeru.
