Vaishnava Samhita. Shri Vyasadasa Charitam II. Vol II Book VI Chp 3 Shlokas 29 - 30

पूरयस्यतिकारुण्यादेवं भक्तमनोरथम् 
प्रतिक्रियां न जानन्ति सर्वे भागवतास्तव  ||
तस्मादेव हि ते भक्तास्त्वामेव शरणं गताः 
अनन्यनिष्ठया देव त्वत्कारुण्यपरायणः   ||

Thus, due to Your supreme mercy You satisfy the bhaktas. The bhagavatas do not know how to reward You for this. That is why Your bhaktas seek only Your mercy and consider it as their only goal in life. Forgetting everything else they surrender unto You.
