This verse illustrates the difference between kṣatriyas and innocent vaiśyas. By studying the political situation, Vasudeva could see what would happen, whereas Nanda Mahārāja, the king of the agriculturalists, could only guess that Vasudeva was a great saintly person and had developed mystic powers. Vasudeva actually had all mystic powers under his control; otherwise he could not have become the father of Kṛṣṇa. But in fact he foresaw the calamities in Vraja by studying Kaṁsa’s political activities and thus warned Nanda Mahārāja to take precautions, although Nanda Mahārāja thought that Vasudeva had predicted this incident through wonderful mystic powers. By mystic powers gained through the practice of haṭha-yoga, one can study and understand the future.
