The author earned fame through his efforts to present the knowledge of Chanakya in contemporary terms so that he could connect ancient principles of governance with modern business and education sectors.

The most acclaimed book written by Pillai is named "Inside Chanakya's Mind". This was a groundbreaking Indian book of nonfiction literature, which discussed the strategic thinking of Chanakya in a contemporary perspective.

With clear writing and practical interpretations, Pillai managed to prove that even concepts which were formulated over two thousand years ago still had profound teachings for the present-day society. His writings appealed to many people who looked for advice derived from Indian philosophy.

Pillai published numerous books throughout his career, such as Corporate Chanakya, Chanakya Neeti, Chanakya in You, Chanakya in Daily Life, Katha Chanakya, Chanakya's 7 Secrets of Leadership, and Art of Winning: The Chanakya Way.

In this way, he succeeded in promoting the concept of Indian business philosophy, as well as in turning Chanakya into a timeless counselor.

More than just a writer, Pillai was a teacher and mentor who encouraged readers to derive practical wisdom from India’s ancient wisdom and apply it to business and life.

In his death, we have lost a great mind, someone who managed to unite ancient philosophy and the modern drive for success. His books will go on to encourage future readers to follow his wise interpretations of Chanakya’s principles.
