I Am Interested In Yoga And Meditation

Mind is everything, cause of happiness/disappointment. if we don't know it properly, then our life is like a beggar who lives whole life sitting on a treasure-chamber, which he never thinks of opening it and simply consider it a rusted one and life long remains as a beggar only, so called things which one think and react as happiness is not truly happiness, True-happiness comes out of no-thinking , it is just a feel of freedom. why this thing coming under meditation bcz when one goes to the state of meditation, then only one can have true feel what exactly happening inside and out. and True-happiness-> no thoughts, disappointment/frustration-> cause of full of thoughts.
