Papaji, also known as H.W.L. Poonja, was a renowned Advaita Vedanta teacher who spread the teachings of non-duality and self-realization to seekers around the world. He was born in 1910 in Punjab, India and spent most of his life in India, where he also taught.

Papaji's teachings were deeply rooted in the Advaita Vedanta tradition, which is one of the six orthodox schools of Hindu philosophy. The word "Advaita" means non-duality, and it emphasizes the concept of oneness or unity between the individual self (Atman) and the universal consciousness (Brahman). Papaji's teachings revolved around the idea that the ultimate truth is the realization of this oneness and that it can be achieved through self-inquiry and surrender to the present moment.

Papaji's teachings gained popularity in the West in the 1990s, and he traveled extensively to Europe, North America, and Australia to spread his message. However, he always maintained a base in India, where he continued to teach and guide seekers. He spent most of his time in the holy city of Lucknow, in northern India, where he had a small ashram called "Sri Poonja Maharaj Ashram."

Papaji's teaching style was simple and direct, and he often used stories and anecdotes to convey his message. He emphasized the importance of self-inquiry and encouraged his students to question their thoughts and beliefs to discover the truth within themselves. He also stressed the importance of surrendering to the present moment and letting go of the ego.

Papaji's teachings attracted people from all walks of life, and his ashram in Lucknow became a hub for seekers from around the world. He taught until his passing in 1997, but his teachings continue to inspire and guide many to this day.

In conclusion, Papaji taught primarily in India, with a base in Lucknow, but also traveled extensively to spread his message of non-duality and self-realization to seekers around the world. His teachings continue to have a profound impact on those who seek to understand the true nature of reality and the self.
