In Buddhist teachings, both samadhi and panna (related to vipassana) are forms of meditation. Samadhi is concentration meditation, to get single-pointed focus on the meditation-object. (often the breath) Panna/Vipassana is insight meditation. You focus on all of the different sensations coming in rapid-fire, like noting 'thought, breath, sound, sound, thought, sound, pressure' as they arise -- like frames of a movie or video game. The Buddha and teachers today often recommend concentration meditation, in order to reach a state of focus, followed by insight meditation, as the natural progression towards stream entry / nirvana.
