Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 40


धिग् जन्म नस्त्रिवृद् यत् तद् धिग्‌व्रतं धिग्‌‌बहुज्ञताम् ।धिक्कुलं धिक् क्रियादाक्ष्यं विमुखा ये त्वधोक्षजे ॥ ४० ॥


dhig janma nas tri-vṛd yat taddhig vrataṁ dhig bahu-jñatāmdhik kulaṁ dhik kriyā-dākṣyaṁvimukhā ye tv adhokṣaje


[The brāhmaṇas said:] To hell with our threefold birth, our vow of celibacy and our extensive learning! To hell with our aristocratic background and our expertise in the rituals of sacrifice! These are all condemned because we were inimical to the transcendental Personality of Godhead.


As explained in the definitions above, the words tri-vṛḍ janma, or “threefold birth,” refer to 1) physical birth, 2) brahminical initiation and 3) initiation into the performance of Vedic sacrifice. Everything is useless if one is ignorant of the Absolute Truth, the Supreme Lord Kṛṣṇa.
