Bankei Yotaku was a Japanese Zen master who lived in the 17th century. He is known for his profound teachings and unique approach to Zen Buddhism. Bankei's philosophy can be summarized in three main principles: the Unborn, the Unexcelled, and the Unsurpassable.

The first principle, the Unborn, refers to the idea that our true nature is pure and untouched by any external influences or experiences. Bankei believed that everyone is born with an innate wisdom and enlightenment, but it becomes clouded by societal and cultural conditioning. He taught that by letting go of these external influences, we can tap into our true nature and experience the inherent peace and happiness within us.

The second principle, the Unexcelled, emphasizes the uniqueness and individuality of each person's journey towards enlightenment. Bankei believed that there is no one-size-fits-all approach to spiritual awakening and that each person must find their own path. He encouraged his students to trust their own experiences and insights rather than blindly following the teachings of others.

The third principle, the Unsurpassable, highlights the idea that enlightenment is not a destination but a continuous journey. Bankei believed that there is no end to spiritual growth and that even after attaining enlightenment, one must continue to cultivate and deepen their understanding. He taught that true enlightenment is not about achieving a state of perfection but rather about embracing imperfection and constantly striving towards self-improvement.

In addition to these three principles, Bankei also emphasized the importance of living in the present moment and letting go of attachments and desires. He believed that suffering arises from our attachment to material possessions, relationships, and even our own thoughts and emotions. By letting go of these attachments, we can free ourselves from suffering and experience true inner peace.

Bankei's philosophy is often described as a blend of traditional Zen Buddhism and the teachings of Pure Land Buddhism. He emphasized the importance of both meditation and devotion in one's spiritual practice. Bankei's teachings continue to inspire many people today, and his philosophy remains relevant in our modern world, where we are often bombarded with external influences and distractions.

In summary, Bankei Yotaku's philosophy is centered around the idea of returning to our true nature, embracing our individual journey towards enlightenment, and living in the present moment. He believed that by letting go of external influences and attachments, we can tap into our innate wisdom and find true happiness and peace within ourselves.
