Therefore the king is repentant.

NOTE. Why should the Vedic scriptural teachings be meticulously observed? Prabhupāda explains thus:

The Vedas are . . . codes of working directions. Anything performed without the direction of the Vedas is called vikarma, or unauthorized or sinful work. Therefore, one should always take direction from the Vedas to be saved from the reaction of work. As one has to work in ordinary life by the direction of the state, one similarly has to work under direction of the supreme state of the Lord. Such directions in the Vedas are directly manifested from the breathing of the Supreme Personality of Godhead. It is said, asya mahato bhūtasya niśvasitam etad yad ṛg-vedo yajur-vedaḥ sāmavedo ’tharvāṅgirasaḥ. “The four Vedas—namely the Ṛg Veda, Yajur Veda, Sāma Veda, and Atharva Veda—are all emanations from the breathing of the great Personality of Godhead.” (Bṛhad-āraṇyaka Upaniṣad 4.5.11) The Lord, being omnipotent, can speak by breathing air, for as it is confirmed in the Brahma-saṁhitā, the Lord has the omnipotence to perform through each of His senses the actions of all other senses. In other words, the Lord can speak through His breathing, and He can impregnate by His eyes. In fact, it is said that He glanced over material nature and thus fathered all living entities. After creating or impregnating the conditioned souls into the womb of material nature, He gave His directions in the Vedic wisdom as to how such conditioned souls can return home, back to Godhead. We should always remember that the conditioned souls in material nature are all eager for material enjoyment. But the Vedic directions are so made that one can satisfy one’s perverted desires, then return to Godhead, having finished his so-called enjoyment. It is a chance for the conditioned souls to attain liberation. (Bhagavad-gītā 3.15 purport)
