As it said in a Chinese proverb:" Disasters always come after fortunes", a good example of impermanence. Neither sensational comforts, nor good relationships and worldly status would last forever in this world. Only a clear recognition of impermanence could liberate us from the endless circle of loosing and grasping, so we can free our mind to pursuit enlightenment, a blissful home of our true nature. As it said in the "Nirvana Sutra": "Away from the circle of life and death, Nirvana is the ultimate blissful stage." Because of this awareness, many ancient masters abandoned worldly status as if they were throwing away garbages. They upheld diligent and ascetic practices for Dharma, and eventually achieved great attainments. As beginners, we should learn from them.
As Dharma practitioners, we cannot be afraid of obscurations such as poverty and sickness, neither should we give up faith on our Buddha and abandon Dharma studies. Because these pains are fields of merits as it said in many Buddhist scriptures and verses. This theory isn't just to comfort your mind, instead you should thoroughly understand it with certainty. In "Diamond Sutra" it says:" If a good man or good woman who accepts, upholds, reads or recites this Sutra is disdained or slandered, if they are despised or insulted, it means that in prior lives they committed evil acts and as a result are now suffering the fruits of their actions, after this, their prior life’s evil acts will finally be extinguished.” Also in the "Great Liberation Sutra" it says: "By practicing patient and great compassion in this world for a short moment, a man can receive same merits as if he upheld pure precepts in a Pure Land for a kalpa. This purifies all karmic burden from his body, speech and mind."
