According to Vedic system, therefore, there is forced renunciation. Nobody wants to retire from family life, but the Vedic injunction is that after one has passed fifty years, he must leave his family life. Pañcāśordhvaṁ vanaṁ vrajet. In the beginning, as a student life, he's trained up, brahmacārī, undergoing severe austerities, penances, and taking instruction from the spiritual master about the temporary existence of this material world. In this way, he's trained up very nicely. And even after training, if he appears to be attached to this material world, he's allowed to go home and marry. And some of the brahmacārīs are allowed to remain naiṣṭhika-brahmacārī, without going home and accepting a wife.
But one who cannot, he's allowed to accept wife and become a householder and remain there for twenty-five years. Because generally, the brahmacārī was going home at the age of twenty-four years, twenty-five years. So after marriage, he may get a child. So living there for twenty-five years means the child is grown up.
Then the husband and wife takes leave—not leaving for good, but vānaprastha, traveling in pilgrimages like Vṛndāvana, Prayāga. That was the system. And after two months, again he comes back and remains home for another two months. Again goes out. In this way, the whole process is how to give up attachment from this family life, from this world. And when he's trained up fully, he takes sannyāsa. That is our Vedic system.
