It is best that busy people today take up the practice of Dzogchen. Even though Dzogchen is for people of superior capacity, we can still try to elevate ourselves to that level, and the way to do that is by practicing the preliminaries. Through hearing and contemplating the Dharma, and the practice of the preliminaries, an ordinary person who knows nothing about karma, let alone renunciation and bodhicitta, can also turn into someone of superior capacity. A person who has cultivated renunciation and bodhicitta after completing the preliminaries and developed great faith in tantra is said to have superior capacity. Such a person has a chance of succeeding in the Dzogchen practice. Whether we can be someone of superior capacity is all up to us. However, to practice Dzogchen prematurely would not only fail to bring any benefit but also run the risk of losing one’s faith in the practice. Therefore, make effort to practice the preliminaries first.
