Does it means Buddhism will make the average follower to feel more suffering?
No. Like every religion there are Buddhists that take the teachings of kamma too seriously or miscomprehend the 1st noble truth, just as some Christians take sin & hell too seriously.
However, most Buddhist love Buddhism & are very happy to have it.
The core of the Buddhist teachings are the four noble truths which
talks about the existence of suffering. Other religions criticize
Buddhism telling that this focusing on suffering makes the followers
to be aware of the existence suffering and to feel more suffering
instead of trying to enjoy the good things life can give us.
This statement is false & mostly pertains to the recent modern political, economic & imperialist phenomena called Protestant-Judaeo-Christianity, whose followers are spiritually blind due to their lust for worldly things.
In other words, the real Christian teachings in the Bible & also historically talked much about the suffering of the world & the giving up of 'worldliness'.
People who believe there are "good things" to enjoy in life are called "worldlings", in both Buddhism & Christianity,
The love of the world is for Judaics & the Crypto-Judaics who call themselves 'Protestant Christians'.
Real Buddhists & Christians seek the bliss of heaven. Jesus said: "My kingdom is not of this world".
One answer Buddhism gives to this review is that, yes suffering exists and we are in a suffering situation but the four noble truths
continues and tells us that it's possible to stop suffering.
This is not a Buddhist answer but a view influenced by fundamentalist religion that tries to present a total view of life.
Buddhism does not state "we are in a suffering situation". Instead, like a doctor waiting for sick people to visit, Buddhism waits for people who are themselves aware of suffering in their life and look for a solution.
On the other hand, suffering is stopped when enlightenment is achieved and yes, it is possible to stop suffering but also very
unlikely even for monks and for an average person that would be even
It is true the majority of people cannot stop all suffering. Buddhism has no illusions about this. When the Buddha reached enlightenment, he said his core teachings, such as the four noble truths, were for the few rather than for the many.
In the Bible, it is reported Jesus said the same, when he said: "The road to life is narrow & only few will enter through the narrow gate".
This said, the Buddha & Buddhism rarely taught the four noble truths to ordinary lay people. Most Asian Buddhist lay people cannot even tell you what the four noble truths are.
Again, it is only a Western academic phenomena that believes the four nobles truths are the be all & end all of Buddhism.
Buddhism has teachings for lay people who, like the Christian Protestants, love the world.
