It is true that one or two can get rid of the 'I' through samadhi; but these cases are very rare. You may indulge in thousands of reasoning, but still the 'I' comes back. You may cut the peepal-tree to the very root today, but you will notice a sprout springing up tomorrow.

Therefore if the 'I' must remain, let the rascal remain as the 'servant I'. As long as you live, you should say, 'O God, Thou art the Master and I am Thy servant.' The 'I' that feels, 'I am the servant of God, I am His devotee' does not injure one. Sweet things cause acidity of the stomach, no doubt, but sugar candy is an exception.
