SB Canto 2

The three activities of religion, economic development and sense gratification are generally attractive for conditioned souls struggling for existence in the material world. Such regulated activities prescribed in the Vedas are called the karma-kāṇḍīya conception of life, and householders are generally recommended to follow the rules just to enjoy material prosperity both in this life and in the next. Most people are attracted by such activities.

SB 2.4.3-4, Translation and Purport

O great sages, the great soul Mahārāja Parīkṣit, constantly rapt in thought of Lord Kṛṣṇa, knowing well of his imminent death, renounced all sorts of fruitive activities, namely acts of religion, economic development and sense gratification, and thus fixed himself firmly in his natural love for Kṛṣṇa and asked all these questions, exactly as you are asking me.

The three activities of religion, economic development and sense gratification are generally attractive for conditioned souls struggling for existence in the material world. Such regulated activities prescribed in the Vedas are called the karma-kāṇḍīya conception of life, and householders are generally recommended to follow the rules just to enjoy material prosperity both in this life and in the next. Most people are attracted by such activities. Even in the activities of their modern godless civilization, people are more concerned with economic development and sense gratification without any religious sentiments. As a great emperor of the world, Mahārāja Parīkṣit had to observe such regulations of the Vedic karma-kāṇḍīya section, but by his slight association with Śukadeva Gosvāmī he could perfectly understand that Lord Kṛṣṇa, the Absolute Personality of Godhead (Vāsudeva), for whom he had a natural love since his birth, is everything, and thus he fixed his mind firmly upon Him, renouncing all modes of Vedic karma-kāṇḍīya activities.
