We loosely talk of Self-realization, for lack of a better term. But how can one realize that which alone is real? All we need to do is to give up our habit of regarding as real that which is unreal. All religious practices are meant solely to help us do this.
Ramana MaharshiMeditation helps concentration of the mind. Then the mind is free from thoughts and is in the meditated form.
Ramana MaharshiEvery living being longs always to be happy, untainted by sorrow; and everyone has the greatest love for himself, which is solely due to the fact that happiness is his real nature. Hence, in order to realize that inherent and untainted happiness, which indeed he daily experiences when the mind is subdued in deep sleep, it is essential that he should know himself. For obtaining such knowledge the inquiry 'Who am I?' in quest of the Self is the best means.
