Srimad-Bhagavatam: Canto 6 - Chapter 1 - Verse 58

Sanskrit:

लब्ध्वेह मानुषीं योनिं ज्ञानविज्ञानसम्भवाम् ।आत्मानं यो न बुद्ध्येत न क्‍वचित्क्षेममाप्नुयात् ॥ ५८ ॥

ITRANS:

labdhveha mānuṣīṁ yoniṁjñāna-vijñāna-sambhavāmātmānaṁ yo na buddhyetana kvacit kṣemam āpnuyāt

Translation:

A human being can attain perfection in life by self-realization through the Vedic literature and its practical application. This is possible especially for a human being born in India, the land of piety. A man who obtains birth in such a convenient position but does not understand his self is unable to achieve the highest perfection, even if he is exalted to life in the higher planetary systems.

Purport:

This statement is confirmed in Caitanya-caritāmṛta (Ādi 9.41). Lord Caitanya said: Everyone born in India, especially as a human being, can achieve the supreme success through the Vedic literature and its practical application in life. When one is perfect, he can render a service for the self-realization of the entire human society. This is the best way to perform humanitarian work.
