SB Canto 3

A good son is called apatya, one who does not allow his father to fall down.

SB 3.1.13, Purport: A good son is called apatya, one who does not allow his father to fall down. The son can protect the father's soul when the father is dead by offering sacrifices to please the Supreme Lord, Viṣṇu. This system is still prevalent in India. After the death of his father, a son goes to offer sacrifices at the lotus feet of Viṣṇu at Gayā and thus delivers the father's soul if the father is fallen. But if the son is already an enemy of Viṣṇu, how, in such an inimical mood, can he offer sacrifice unto Lord Viṣṇu's lotus feet? Lord Kṛṣṇa is directly the Personality of Godhead, Viṣṇu, and Duryodhana was inimical to Him. He would therefore be unable to protect his father, Dhṛtarāṣṭra, after his death. He himself was to fall down because of his faithlessness towards Viṣṇu. How, then, could he protect his father? Vidura advised Dhṛtarāṣṭra to get rid of such an unworthy son as Duryodhana as soon as possible if he was at all anxious to see to the good of his family. According to the moral instructions of Cāṇakya Paṇḍita, "What is the use of a son who is neither a learned man nor a devotee of the Lord?" If a son is not a devotee of the Supreme Lord, he is just like blind eyes—a source of trouble. A physician may sometimes advise the extrication of such useless eyes from their sockets so that one can be relieved of the constant trouble. Duryodhana was exactly like blind, troubling eyes; he would be a source of great trouble to the family of Dhṛtarāṣṭra, as foreseen by Vidura. Vidura therefore rightly advised his eldest brother to get rid of this source of trouble. Dhṛtarāṣṭra was wrongly maintaining such personified offense under the mistaken impression that Duryodhana was a good son, able to liberate his father.

SB Canto 4

The purpose of marriage, therefore, is to have a putra, or son who is able to deliver his father, even if the father falls down to the hellish condition of put.

SB 4.21.46, Purport: According to the Vedic version, there is a hellish planet called Put, and one who delivers a person from there is called putra. The purpose of marriage, therefore, is to have a putra, or son who is able to deliver his father, even if the father falls down to the hellish condition of put. Mahārāja Pṛthu's father, Vena, was a most sinful person and was therefore cursed to death by the brāhmaṇas. Now all the great saintly persons, sages and brāhmaṇas present in the meeting, after hearing from Mahārāja Pṛthu about his great mission in life, became convinced that the statement of the Vedas had been fully proved. The purpose of accepting a wife in religious marriage, as sanctioned in the Vedas, is to have a putra, a son qualified to deliver his father from the darkest region of hellish life. Marriage is not intended for sense gratification but for getting a son fully qualified to deliver his father. But if a son is raised to become an unqualified demon, how can he deliver his father from hellish life? It is therefore the duty of a father to become a Vaiṣṇava and raise his children to become Vaiṣṇavas; then even if by chance the father falls into a hellish life in his next birth, such a son can deliver him, as Mahārāja Pṛthu delivered his father.
