Eminent social worker Avinash Rai Khanna is a remarkable thinker. A former Member of Parliament and an active politician, he has been working intensely on social issues and raised them in Parliament from time to time. These social issues are in no way connected to politics. These in fact present deep thinking and an earnest relationship with ground realities. Each of the nine chapters of this book showcases an outlook on pertinent social issues. From the ever-changing evils of society and how together we can solve day-to-day problems to what the responsibility of society towards orphans should be and how to prevent their criminalization have been discussed threadbare. Khanna has selected topics unrelated to politics and governments, addressing the smallest unit of a nation - the family. He attributes problems to the departure from India's roots and highlights instilling the nation's ageold cultural ethos among children. Khanna hails from Punjab where, in the recent decades drug addiction among the young population has emerged as a significant problem. In his article 'How to get rid of drug addiction', Khanna presents a solution to this very problem. The author also considers military training in tandem with formal education an important input for nation-building. Overall, this succinct bouquet of thinking - Samajik Chintan, is an inspiring treatise for all..
