जीवाजीवविभत्तिं, सुणेह मे एगमणा इओ ।
जं जाणिऊण भिक्खू, सम्मं जयइ संजमे ॥३६.१॥
Listen to this classification of living and non-living with a one-pointed mind. The monk who truly knows this strives correctly in restraint.
The opening verse sets the entire purpose of the chapter: this is not academic philosophy but practical liberation knowledge. The word egamaṇā — one-pointed mind — demands full attention, because half-understood knowledge leads to half-correct conduct. The monk who knows precisely what is a living soul and what is not can act with the precision that non-violence requires. Restraint (saṃyama) practiced without this knowledge is blind; with it, it becomes the exact science of liberation.
The simple version: Listen carefully. A monk who truly understands what is living and what is non-living will practice restraint correctly.
