Immersion
A very short instruction at Sāvatthī. The Buddha tells the mendicants to develop immersion, the translation’s word for samādhi, a settled and unified mind. One who has immersion truly understands, and what they understand is stated in four parts: this is suffering, this is its origin, this is its cessation, and this is the practice that leads to its cessation. He repeats the instruction to develop immersion and closes by saying that this is why they should practise meditation: to understand these four things.
