Shingon, also known as Esoteric Japanese Buddhism, is a unique and distinct form of Buddhism that originated in Japan in the 9th century. It is based on the teachings of the Indian Buddhist monk, Kukai, who traveled to China and studied Esoteric Buddhism, also known as Vajrayana, before bringing it back to Japan.

One of the main differences between Shingon and other forms of Buddhism is its emphasis on the practice of esoteric rituals and mantras. These practices are believed to have the power to transform one's consciousness and lead to enlightenment in this lifetime. In contrast, other forms of Buddhism may focus more on meditation and self-reflection.

Another key difference is the belief in the importance of the physical body in spiritual practice. In Shingon, the body is seen as a sacred vessel that can be purified and empowered through the use of mudras (hand gestures), mantras, and visualization techniques. This is in contrast to other forms of Buddhism that may view the body as a temporary and ultimately unimportant aspect of existence.

Shingon also places a strong emphasis on the role of the guru or teacher in spiritual development. In this tradition, it is believed that a qualified guru is necessary to transmit the teachings and empower the student with the necessary tools for enlightenment. This is in contrast to other forms of Buddhism, such as Zen, which emphasize the individual's own efforts in achieving enlightenment.

Additionally, Shingon has a unique cosmology that includes the belief in multiple Buddhas and deities, each with their own specific attributes and powers. These beings are seen as manifestations of the ultimate reality and are worshipped and invoked in rituals and ceremonies.

Finally, Shingon also has a strong connection to Japanese culture and incorporates elements of Shintoism, the indigenous religion of Japan. This can be seen in the use of sacred objects and symbols, as well as the integration of nature and natural elements into spiritual practice.

In conclusion, Shingon is a distinct form of Buddhism that sets itself apart from other traditions through its emphasis on esoteric practices, the importance of the physical body, the role of the guru, its unique cosmology, and its connection to Japanese culture. Its rich and complex teachings continue to attract followers and practitioners in Japan and around the world.
