शुकदेव उवाच
वृथा त्वं क्लिश्यसे बाल बहुभिर्योगसाधनैः |
पुरस्थितेपि भक्तानां सुलभे नन्दनन्दने ||
न तुष्यति कृपासिन्धुर्गोपालो रसवर्धनः |
विहाय प्रेमवात्सल्यं रचितैः शुष्कसाधनैः ||
तस्मादबृन्दावनं प्राप्य गोपालं भज सन्ततम् |
तवत्प्रेमविवशः कृष्णो नूनामाविभविष्यति ||
Shri shukadeva said
My child! Why do you strain yourself in vain even when Shri Nandakumara the bhaktavatsala easily accessible to the bhaktas, is standing in front of you? The merciful Lord Shri Gopala who enhances the ecstasy of Bhakti, is not getting pleased with dry and worn out yogic and other practices. Hence, go to Shri Brindavan, and do bhajan on Shri Gopala. Certainly Shri Krishna will be enchanted by your loving devotion and bless you with His darshan.
