Dear Shri Yamaka,
True peace is achieved by shunning than by seeking. If you do not perceive the need for something where is the question of losing your peace in not possessing it? On the other hand if you seek something your mind does not rest till you possess it. Even if you possess it, peace is lost if you lose it. This is true with respect to both tangible and intangible possessions.
Science teaches you to seek whereas religion teaches you to shun.
Dear Sravna:
I am a seeker, not a "shunner". I walk into controversies with the intent to solve them! I tend to think that I am a Problem Solver.
What gives me peace? "Proper" understanding of issues and when I propose solutions for problems.
What gives me most happiness? When my working hypothesis turns out to be correct, after experimentation. When I do this, I gather "bragging rights"!!
Personally, when I look back in my life and career, I have been a winner; therefore, I have all reasons to be happy and peaceful...
Disclosure: I have been an Atheist in the past 40 years... I reject Poorva Janma Karma Theory!
Peace.
