In order to free from suffering, one should know the cause of it. Without reaching at the cause it will really be difficult to overcome the effects generated from.
When a man knows the causes of the suffering, it becomes easy for him to know the means of removing it.
If the cause is removed, the effects get removed and this is the logic of nature which one needs to understand all well.
Basic cause of any suffering is lack of discriminative knowledge; in-discriminative knowledge is wrong which leads to suffering.
They who regard truth and saintly wisdom attain discriminative knowledge to counter the sufferings of life.
May lord bless all.
