There are two kinds of general activities-śreyas, or activities which are ultimately beneficial and auspicious, and preyas, or those which are immediately beneficial and auspicious. For example, children are fond of playing. They don’t want to go to school to receive an education, and they think that to play all day and night and enjoy with their friends is the aim of life. Even in the transcendental life of Lord Kṛṣṇa, we find that when He was a child He was very fond of playing with His friends of the same age, the cowherd boys. He would not even go home to take His dinner. Mother Yaśodā would have to come out to induce Him to come home. Thus it is a child’s nature to engage all day and night in playing, not caring even for his health and other important concerns. This is an example of preyas, or immediately beneficial activities. But there are also śreyas, or activities which are ultimately auspicious. According to Vedic civilization, a human being must be God conscious. He should understand what God is, what this material world is, who he is, and what their interrelationships are. This is called śreyas, or ultimately auspicious activity.
