Watching what interactions, events, thoughts do to you is quite interesting. Imagine a calamity; suffering people, shortage of basic needs, uncertainty and hopelessness. As if to defy the adversity, one witnesses love and concern, selfless service, generosity without an expectation of reciprocation. Innumerable instances can be recounted. Now imagine prosperity. Almost inevitably, one witnesses fear of loss, discontent, greed and insensitivity.
The same person is capable of exhibiting these contrarian behaviours. Many in our generation have spent years sharing a single room with the entire family, who are now intolerant to the same family members staying in a separate room under the same roof. May be, adversary kills the ego and prosperity feeds it, and a well fed ego in turn causes adversity. My sense is that this cycle is a natural process and cannot be broken however much one wishes or hopes. Not in every case, but as a rule.
