There are three kinds of Dharma practitioners, who can be categorized as
1. Ordinary kind of practitioners—they practice the Dharma in order to
achieve happiness in this life. Such a practitioner still has the confidence
that there is indeed happiness in samsara.
2. Medium kind of practitioners—they practice the Dharma in order to attain
Arhat-hood for their own release from samsara, while there are still many
sentient beings suffering in samsara.
3. Excellent kind of practitioners—they are the ones who practice for the sake
of helping all sentient beings attain enlightenment. They practice not only for
their own liberation but also for that of others.
Depending on the vastness of the individual level of motivation, these three
kinds of practitioners appear. For instance, if a practitioner recites the
Avalokiteshvara mantra "Om Mani Padme Hung" for his own happiness, he thus falls
into the category of "Ordinary Practitioner." Similarly, a "Medium Practitioner"
will recite the mantra for his own liberation and an "Excellent Practitioner"
will recite the mantra for the liberation of all sentient beings.
