The "Connected Discourses on Collectedness" contains teachings on the four jhānas—states of mental composure where awareness is gathered and steady. These discourses emphasize how cultivating jhānas leads a practitioner to slant, slope, and incline towards Nibbāna. Through the progressive deepening of collectedness—from reflection and examination to equanimity and purification of mindfulness—these teachings reveal the transformative power of cultivating this stable, undistracted awareness on the path to liberation.
