Śrīmad-Bhāgavatam · Text 10.14.32
Who is speaking and story frame
अहो भाग्यमहो भाग्यं नन्दगोपव्रजौकसाम् ।
यन्मित्रं परमानन्दं पूर्णं ब्रह्म सनातनम् ॥ ३२ ॥
aho bhāgyam aho bhāgyaṁ
nanda-gopa-vrajaukasām
yan-mitraṁ paramānandaṁ
pūrṇaṁ brahma sanātanam
How greatly fortunate are Nanda Mahārāja, the cowherd men and all the other inhabitants of Vrajabhūmi! There is no limit to their good fortune, because the Absolute Truth, the source of transcendental bliss, the eternal Supreme Brahman, has become their friend.
