古鲁 (Teacher) refers to a person who imparts knowledge, skills, and values to students. In many cultures, teachers play a crucial role in shaping the minds of future generations. They often work in various educational settings, such as schools, colleges, and universities, and may specialize in different subjects. The concept of a teacher is not limited to formal education. In some traditions, such as 佛教 (Buddhism), a teacher, or 上师 (Shifu), guides students on spiritual paths. This highlights the importance of mentorship and guidance in both academic and personal development.
