Shingon, also known as Esoteric Japanese Buddhism, is a form of Buddhism that originated in Japan in the 9th century. It is based on the teachings of the Indian Buddhist master, Kukai, who traveled to China to study Esoteric Buddhism and brought it back to Japan. Shingon places a strong emphasis on ritual and meditation, and has a complex system of deities and practices.

In Shingon, there are specific ethical guidelines and principles that guide the behavior and actions of practitioners. These guidelines are based on the Buddhist concept of the Eightfold Path, which includes principles such as right speech, right action, and right livelihood. However, Shingon also has its own unique set of ethical principles that are specific to its esoteric practices.

One of the main ethical principles in Shingon is the concept of "non-harming" or "ahimsa." This principle is based on the Buddhist belief in the interconnectedness of all beings and the importance of showing compassion and kindness towards others. Practitioners are encouraged to avoid causing harm to any living being, whether it be through physical, verbal, or mental actions. This principle is also extended to the environment, with practitioners being encouraged to live in harmony with nature and to minimize their impact on the earth.

Another important ethical principle in Shingon is the concept of "right intention." This refers to the intention behind one's actions, and emphasizes the importance of having pure and positive intentions. Practitioners are encouraged to cultivate a mind of compassion, wisdom, and selflessness in all their thoughts and actions. This principle is closely tied to the concept of karma, which teaches that our actions have consequences and can impact our future experiences.

In addition to these overarching ethical principles, Shingon also has specific guidelines for its esoteric practices. These guidelines include the importance of maintaining a pure and focused mind during ritual and meditation, as well as the proper handling and use of ritual objects and symbols. Practitioners are also expected to be respectful and mindful when interacting with their teachers and fellow practitioners.

Overall, the ethical guidelines and principles in Shingon serve to guide practitioners towards leading a moral and compassionate life, both in their spiritual practices and in their daily interactions with others. By following these principles, practitioners can cultivate a sense of inner peace and harmony, and contribute to creating a more compassionate and harmonious world.
