The Buddha revealed His Dharma for the purpose of developing the spiritual power of sentient beings
And teaching them how to perceive the problems of the material world.
The Dharma is to be applied to discover enlightenment among one’s worries and distress,
To distinguish good from evil,
And to find principles in ordinary things.
To put it simply,
The Dharma is to help sentient beings to break through their delusions and attain the enlightenment.
To tolerate wholeheartedly, to repent honestly, and to assume responsibilities serenely
Are the ways to destroy the attachment to one’s ego, to develop one’s enlightenment, and to attain the ultimate goal of becoming fully enlightened.
In other words, these are the true ways to practice Buddhism.
An illiterate person can also practice Buddhism
And understand the teachings of the Buddha
As long as he/she can diligently commit himself/herself to “learn, meditate, and practice” the teachings of the Buddha.
However, if one does not fully comprehend the teachings of the Buddha,
He/She will never attain the Buddhahood.
