The point of Dharma is liberation from suffering.
What was explained to me is that all beings look for liberation from suffering.
They want to be free from fear, danger, hunger, etc.
And ultimately, what all beings want is perfect liberation, perfect "happiness"
meaning that once they are free from suffering, there will not be a return to suffering.
But since beings rely on things which do not uproot the causes of suffering,
even if they get some relief, it is only temporary.
Relying on is also called taking refuge in.
In other words, usually people take, as objects of refuge, things such as money or possessions
thinking that these things will bring them perfect happiness.
but the money runs out, or they get bored with what they have acquired
and the suffering returns.
But Buddhists take refuge in the Buddha, Dharma & Sangha,
because this path perfectly uproots the causes of suffering.
So, the issue isn't that Buddhism doesn't encompass more than this.
It teaches a lot about compassion and calming the mind, patience, generosity, kindness, ethical conduct, etc.
things which anyone can benefit from regardless of whether they take refuge in the three jewels or not.
In that respect, sure, it makes a lot of sense. Buddhism doesn't hold a monopoly on those things.
But if one still looks for the perfect cessation of suffering in things that don't uproot the causes of suffering,
even performing all those good activities will only bring temporary results.
Profile Picture: "The Foaming Monk"
The Chinese characters are Fo (buddha) and Ming (bright). The image is of a student of Buddhism, who, imagining himself to be a monk, and not understanding the true meaning of the words takes the sound of the words literally. Likewise, People on web forums sometime seem to be foaming at the mouth. Original painting by P.Volker /used by permission.
