Letters of Sri Aurobindo
Volume 1
As regards the progress you have made, I do not think you have given us an exaggerated impression of it; it seems to be quite real. It is no part of the Yoga to suppress taste, rasa, altogether; so, if you found the ice-cream pleasant, that does not by itself invalidate the completeness of your progress. What is to be got rid of is vital desire and attachment, the greed of food, being overjoyed at getting the food you like, sorry and discontented when you do not have it, giving an undue importance to it, etc. If one wants to be a Yogin, it will not do to be like the ordinary man to whom food, sex 
and gain are nine-tenths of life or even to keep in any of these things the reactions to which vital human nature is prone. Equality is here the test as in so many other matters. If you can take the Ashram food with satisfaction or at least without dissatisfaction, that is already a sign that attachment and predilection are losing their old place in the nature. It is also an excellent sign if empty social meetings are no longer attractive,– a sure sign that the psychic and the Yogic consciousness are gaining ground. As for sex, the progress you report is also excellent; sex is almost the strongest of human vital pulls and to master it altogether takes time, but here too a good beginning is half the battle.
For the rest, I had told you that even when people do not seem to be progressing outwardly a preparatory work is often being done behind the veil and that this was your case. When the preparation is complete, then one day one wakes up to find that, without having noticed it, a large stride forward has been made.
As for scepticism, that disease of the age that is passing away, it is another story and I will deal with it perhaps some other time. I will now only say that discrimination is an excellent element in Yoga, but scepticism is the reverse; it poses as an exacting discrimination, but is only an exaggerated caricature of the real thing. Saṃśaya [doubt], aśraddhā [lack of faith] are not viveka [discrimination, discernment].
