The Buddha once said that his teaching directed us toward three principles: sila (ethical conduct), panna (wisdom), and samadhi (firmness of mind). Samadhi is the fundamental principle of a steady and harmonious mind. During samadhi, consciousness is not wavering with each thought but firm and stationary, allowing attention to be bare and free for observation. There is a component of wisdom within samadhi since the mind is resolute and unperturbed by states of mind, yet there is a difference between samadhi and awareness. Awareness is not a state of mind and samadhi is a conditioned state that changes over time; awareness is more easily acknowledged when the mind is firm and steady.
