Good question Vinodh.
If discontentment and unhappiness were the sole sources of progress, then places like Ethiopia and Somalia would have progressed far ahead of the rest of the world -- but they have not. Guruji says silence, not discontentment, is the true source of creativity and resourcefulness. The contentment he teaches is not a passive or resigned form of contentment; it is lively and supports progress.
The same is his guidance on protesting injustice. Most protest movements are grounded in deep discontentment. That sentiment, when taken to an extreme, leads to terrorism. Instead, he says, be grounded in spiritual values, and keep doing your bit to effect change from that space of
sattva.
Art of Living has played an active role in "India Against Corruption". The following video is of Anna Hazare, Guruji, Arvind Kejriwal, and Swami Agnivesh in satsang. It's 40 minutes long but worth watching, Shraddha and I watched it over breakfast yesterday. All Hindi, no subtitles (sorry).
