Meditation (Pali: Bhavana) means the positive reinforcement of one's mind. Broadly categorized into Samatha and Vipassana, Meditation is the key tool implemented in attaining jhana. Samatha literally means "to make skillful", and has other renderings also, among which are "tranquilizing, calming", "visualizing", and "achieving". Vipassana means "insight", or "abstract understanding". In this context, Samatha Meditation makes a person skillful in concentration of mind. Once the mind is sufficiently concentrated, Vipassana allows one to see through the veil of ignorance.
