3.19.36

तं सुखाराध्यमृजुभिरनन्यशरणैर्नृभि: । कृतज्ञ: को न सेवेत दुराराध्यमसाधुभि: ॥ ३६ ॥

krta-jnah

duraradhyam

asadhubhih
by the nondevotees.

What grateful soul is there who would not render his loving service to such a great master as the Personality of Godhead? The Lord can be easily pleased by spotless devotees who resort exclusively to Him for protection, though the unrighteous man finds it difficult to propitiate Him.
