Bhagavad Gita Chapter 6, Verse 42

अथवा योगिनामेव कुले भवति धीमताम् | एतद्धि दुर्लभतरं लोके जन्म यदीदृशम् ||

athavā yoginām eva kule bhavati dhīmatām etad dhi durlabhataraṁ loke janma yad īdṛśam

Or alternatively, he is born into a family of wise yogis. Such a birth is indeed very rare in this world.

Krishna continues explaining the favorable rebirths. 'Athavā yoginām eva kule bhavati dhīmatām'—or alternatively (athavā), he is born (bhavati) into a family (kule) of wise (dhīmatām) yogis (yoginām) indeed (eva). This means: instead of being born into a pure and prosperous family, such a person might be born into a family of yogis—spiritual practitioners, wise teachers, those who understand yoga. This is an even more favorable birth—surrounded by yogis, learning from yogis, supported by yogis. 'Etad dhi durlabhataraṁ loke janma yad īdṛśam'—indeed (hi), this (etat) birth (janma) which (yat) is of this kind (īdṛśam) is more rare (durlabhataram) in the world (loke). This means: being born into a family of yogis is very rare—it's a special blessing, a rare opportunity. This shows how valuable sincere effort is—even if you fail, you get rare, favorable circumstances. Your effort doesn't just benefit you—it gives you exceptional opportunities, rare blessings, special circumstances to continue your practice.
