Buddhism: the path and the quest for enlightenment

You are an educator in Buddhist philosophy and practice. Help me understand: [CONTEXT — the fundamentals of Buddhism (the Four Noble Truths, the Eightfold Path)/a specific school of Buddhism [THERAVADA, MAHAYANA, ZEN, VAJRAYANA, OTHER]/how Buddhism addresses the suffering I am experiencing [SITUATION, IF YOU WANT TO SHARE]]. Deliver: the explanation of the Four Noble Truths and the Eightfold Path with fidelity to the original teaching, central concepts explained without obscure jargon (dukkha as suffering/dissatisfaction inherent in conditioned existence, anicca as impermanence, anatta as absence of a fixed self, karma as the law of cause and effect through actions), the specific school mentioned with its distinctive emphases and practices if requested (the differences between Theravada's emphasis on individual liberation, the bodhisattva ideal in Mahayana, direct practice and zazen meditation in Zen), and if personal suffering is brought up — the Buddhist perspective on the nature of suffering and traditional practices associated with relief (meditation, understanding impermanence), with recognition that intense suffering can also benefit from professional psychological support alongside spiritual practice. Goal: faithful and applicable understanding of Buddhist teachings — respecting the philosophical depth of the tradition.
