Srimad Bhagavatam Canto 06, Chapter 16, Text 58

SB 6.16.58

labdhveha manusim yonim
 jñana-vijñana-sambhavam
atmanam yo na buddhyeta
 na kvacit ksemam apnuyat
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
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 by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
This statement is confirmed in Caitanya-caritamrta (Adi 9.41). Lord Caitanya said:
 
bharata-bhumite haila manusya-janma yara
 janma sarthaka kari’ kara para-upakara
 
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.
