Sadhguru Jaggi Vasudev, commonly known simply as Sadhguru, is an Indian spiritual teacher, yogi, and mystic whose work seeks to bring classical yogic wisdom into contemporary life. Born in Mysore, Karnataka, he presents himself as a modern exponent of ancient spiritual disciplines, emphasizing inner transformation through yoga, meditation, and self-awareness. His teachings frequently highlight individual responsibility for one’s inner state and the primacy of direct experiential knowledge over inherited belief systems.

He is the founder of the Isha Foundation, a non-profit organization headquartered at the Isha Yoga Center near Coimbatore in Tamil Nadu. Through this foundation, he offers a variety of yoga and meditation programs, including structured courses that combine spiritual practices with practical tools for living. The organization also runs educational, social, and rural outreach initiatives, reflecting an understanding of spirituality that is not confined to personal practice but extends into service and social engagement.

Sadhguru’s public presence is extensive: he speaks at international forums, universities, and large public gatherings, and reaches many people through books, talks, interviews, and online platforms. His writings, such as those that explore “inner engineering” and mystical inquiry, aim to make subtle yogic principles accessible to those who may not be rooted in traditional spiritual cultures. The language he employs often draws on psychological and quasi-scientific modes of explanation, seeking to bridge the gap between ancient insight and modern sensibilities.

A distinctive feature of his work is the integration of ecological concern into spiritual life. He has initiated and led large-scale environmental campaigns, including efforts focused on rivers and soil, presenting care for the natural world as an expression of inner balance and responsibility. In this way, his role as a spiritual teacher extends beyond personal enlightenment to encompass a vision of human beings as custodians of the larger web of life.

At the same time, both Sadhguru and the Isha Foundation have attracted criticism and controversy, including questions about certain claims and aspects of the organization’s activities. Supporters regard him as a transformative guide who offers powerful tools for self-realization, while critics scrutinize his methods and statements. This polarity of perception is itself characteristic of many prominent spiritual figures, whose work challenges established frameworks and invites both devotion and debate.
