It is the duty of enlightened souls to deliver the fallen ones, and Vidura came for that reason. But talks of spiritual enlightenment are so refreshing that while instructing Dhṛtarāṣṭra, Vidura attracted the attention of all the members of the family, and all of them took pleasure in hearing him patiently. This is the way of spiritual realization. The message should be heard attentively, and if spoken by a realized soul, it will act on the dormant heart of the conditioned soul. And by continuously hearing, one can attain the perfect stage of self-realization.
