Because of my vow on the verge of death, I have given up even drinking water, yet because I am drinking the nectar of topics about Kṛṣṇa, which is flowing from the lotus mouth of your Lordship, my hunger and thirst, which are extremely difficult to bear, cannot hinder me.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
नैषातिदुःसहा क्षुन्मां त्यक्तोदमपि बाधते । पिबन्तं त्वन्मुखाम्भोजच्युतं हरिकथामृतम्
naiṣātiduḥsahā kṣunmāṃ tyaktodamapi bādhate | pibantaṃ tvanmukhāmbhojacyutaṃ harikathāmṛtam
