Dharmachakrapravartana Sutra ("Turning the Dharma Wheel") Samyutta Nikaya 57.11
Four Noble Truths (catvāri āryasatyāni)
• Suffering (duḥkha)
• Its accumulation (samudaya) - via craving (tṛ́ṣṇā)
• Its cessation (nirodha)
• The Path (mārga) leading to its cessation
Also note:
In order to destroy the Four Inversions (viparyāsa), the Buddha preached the Four Foundations of Mindfulness. The Four Inversions are: - mistaking impermanence (anicca) for being permanent (nitya); - mistaking suffering (dukkha) for bliss (sukha); - mistaking the detestable (asubha) for loveable (śuci); - mistaking what has no-self (anātma) as having a self (ātma).
