Bhagavad Gita 6.42

Or he is born in a family of even the wisest of yogis; verily, such a birth is very difficult to obtain in this world.

Or, he may be born in the family of wise sages, though such a birth is indeed very difficult to obtain.

Or, he is born in the family of wise yogis. Such a birth is indeed more difficult to come by in the world.

अथवा (वैराग्यवान्) योगभ्रष्ट ज्ञानवान् योगियोंके कुलमें ही जन्म लेता है। इस प्रकारका जो यह जन्म है, यह संसारमें बहुत ही दुर्लभ है।
