“The Handbook of Wellness” aims to be a comprehensive, practical guide for achieving holistic well-being — physical, mental, social, and beyond. According to its description, the book “addresses various facets of wellness, ranging from physical health to overall well-being.” 
The book is structured to cover multiple “dimensions of wellness,” ranging from physical, mental, emotional to social, occupational, financial, spiritual, and environmental wellness. In that sense, it embraces a holistic view of health — not just absence of disease, but a balanced, well-rounded, sustainable lifestyle. 
A significant strength of the book is its practical orientation: it doesn’t just present theoretical ideas — it encourages healthy habits, lifestyle changes (including suggestions around nutrition and maybe yoga or wellness practices), and methods to manage stress, mental & emotional well-being, work–life balance, and even environmental and social aspects of wellness. 
Because the book invites contributions from researchers, nutritionists, naturopaths, psychologists and more (as per a “call for chapters” note) — it seems designed to be useful not only for lay readers but also for professionals, academicians and people interested in evidence- or experience-based wellness knowledge. 
For a reader in India, especially those juggling modern stresses, busy lifestyle or exposure to urban life pressures, this book offers a broad roadmap — combining insights on mental health, social relationships, lifestyle balance, nutrition, preventive health, and overall holistic well-being.
In short: “The Handbook of Wellness” by Dr. Praveen Katiyar attempts to present a well-rounded, accessible, and actionable guide to wellness — integrating many dimensions of health and well-being, making it a potentially valuable resource for anyone seeking a balanced, healthy life.
