According to Osho, we do not choose our families; unconscious death propels us robotlike into a womb that matches our unawareness and karmic deserving—'what fits you' receives you. Only a buddha, dying consciously, can choose. Your past life pushes you into a certain family. Cultivating awareness—especially through conscious love—prepares you to die consciously and thus to choose.
You didn’t pick your family; your unconscious state pulled you to parents like you, and by becoming aware now you can gain choice in the future.
