Buddhist meditation
The main goal of Buddhist meditation is to reach nirvana.
The nirvana is a sense where one is freed from all ties and does not have to live through the cycle of life. Meditation is a set of skills through which a Buddhist can be in the state of nirvana.
However, for the most part, meditation is a way to nourish the mind. Buddhism promotes meditation as a way of to reaching the state of mindfulness. Mindfulness is that feeling where the being is fully cognizant of his states of mind. He is aware of every one of his thoughts and each reply entering and leaving his mind. He understands himself much more than an normal person.
There are four noble truths of Buddhism and meditation. These make the basic teaching of the Buddha.
