Samadhi is a state of deep concentration that is achieved through meditation. It's an experience of inner peace and joy, where you become one with the universe and are able to look at the world and yourself without judgment. To reach samadhi, you need to focus your thoughts on something positive and keep your mind very still. Through meditation and practice, samadhi can be reached and you can experience clarity of the mind, tranquility and connectedness with all that is.
