In the West, meditation has been marketed as a relaxation technique — a way to reduce stress and improve productivity. There is nothing wrong with this, but it is like using a telescope to hammer nails.
Buddhist meditation is a technology for seeing reality clearly. The word for meditation in Pali is bhāvanā, which literally means "cultivation" or "development." You are cultivating the mind the way a farmer cultivates a field — clearing away weeds (delusion), planting seeds (insight), and patiently waiting for the harvest (wisdom).
There are two main streams of Buddhist meditation:
Samatha (calm abiding) — training the mind to focus on a single object (the breath, a word, a visualization) until it becomes deeply concentrated and still.
Vipassana (insight) — once the mind is settled, turning that concentrated attention toward the nature of experience itself. Watching thoughts arise and pass. Noticing sensations without grasping. Seeing impermanence directly, not as an idea but as a lived reality.
Both traditions lead, ultimately, to the same insight: nothing you can observe is permanent, and nothing you can observe is your true self.
