यस्य देवे परा भक्तिर्यथा देवे तथा गुरौ
तस्यैते कथिता ह्यर्थाः प्रकाशन्ते महात्मनः

जिसकी ईश्वर एवं महापुरुष में परा भक्ति होती है, वह उस परम तत्त्व को प्राप्त कर सकता है। अर्थात ईश्वर को समर्पित करके कर्म करना चाहिए। (कृपालु जी)
IAST transliteration
yasya deve parā bhaktiryathā deve tathā gurau
tasyaite kathitā hyarthāḥ prakāśante mahātmanaḥ
English meaning
Only to one who has implicit faith in both the spiritual master and the Supreme Lord, are all the imports of the Vedic literature automatically revealed. The great spiritual masters apart from delivering the science intact, without speculative interpretation, lived and demonstrated the teachings of the Vedic literature. (Srila Prabhupada Ji)
