Following is an article from Swami Vivekananda's Complete Works on Practical Vedanta
There is this strongly conservative tendency in human nature: we do not like to move one step forward. I think of mankind just as I read of persons who become frozen in snow; all such, they say, want to go to sleep, and if you try to drag them up, they say, "Let me sleep; it is so beautiful to sleep in the snow", and they die there in that sleep. So is our nature. That is what we are doing all our life, getting frozen from the feet upwards, and yet wanting to sleep. Therefore you must struggle towards the ideal, and if a man comes who wants to bring that ideal down to your level, and teach a religion that does not carry that highest ideal, do not listen to him. To me that is an impracticable religion. But if a man teaches a religion which presents the highest ideal, I am ready for him. Beware when anyone is trying to apologise for sense vanities and sense weaknesses. If anyone wants to preach that way to us, poor, sense-bound clods of earth as we have made ourselves by following that teaching, we shall never progress. I have seen many of these things, have had some experience of the world, and my country is the land where religious sects grow like mushrooms. Every year new sects arise. But one thing I have marked, that it is only those that never want to reconcile the man of flesh with the man of truth that make progress. Wherever there is this false idea of reconciling fleshly vanities with the highest ideals, of dragging down God to the level of man, there comes decay. Man should not be degraded to worldly slavery, but should be raised up to God.
