There are no impediments to meditation. The very thought of such obstacles is the greatest impediment.
Ramana MaharshiMeditation helps concentration of the mind. Then the mind is free from thoughts and is in the meditated form.
Ramana MaharshiThe 'I' casts off the illusion of the 'I' and yet remains 'I'. Such is the paradox of Self-realization. The Realized do not see any paradox in it. Consider the case of the worshipper. He approaches God and prays to be absorbed in Him. He then surrenders himself in faith and by concentration. And what remains afterwards? In the place of the original 'I', self-surrender leaves a residuum of God in which the 'I' is lost. That is the highest form of devotion or surrender and the peak of detachment.
