"Whatever tends to lighten one's burden must be examined carefully. For although such alleviation is sometimes justified and reasonable, it is most often a deceitful prescription of the evil inclination, and must, therefore, be subjected to much analysis and investigation."

“Mesilat Yesharim Hebrew/English translation”

“Though the beginnings and foundations of saintliness are implanted in every person's heart, if he does not occupy himself with them, he will witness details of saintliness without recognizing them and he will trespass upon them without feeling or perceiving that he is doing so. For sentiments of saintliness, fear and love of God, and purity of heart are not so deeply rooted within a person as to obviate the necessity of his employing certain devices in order to acquire them.”

“I have written this work not to teach men what they do not know, but to remind them of what they already know and is very evident to them, for you will find in most of my words only things which most people know, and concerning which they entertain no doubts. But to the extent that they are well known and their truths revealed to all, so is forgetfulness in relation to them extremely prevalent. ... It is possible that the reader will find that he has learned little after having read it that he did not know before. Its benefit is to be derived, rather, through review and persistent study, by which one is reminded of those things which, by nature, he is prone to forget and through which he is caused to take to heart the duty that he tends to overlook.”

“There is also no lack of deterrents which keep saintliness at a distance from a person, but then again there is no lack of devices by which these deterrents may be held afar.”

“All of the character traits, which are in such great need of correction and cultivation—who will cultivate and correct them if we do not give heart to them and subject them to exacting scrutiny?”

“If man had been created solely for the sake of this world, he would have had no need of being inspired with a soul so precious and exalted as to be greater than the angels themselves, especially so in that it derives no satisfaction whatsoever from all of the pleasures of this world. ... "What is this analogous to? To the case of a city dweller who married a princess. If he brought her all that the world possessed, it would mean nothing to her, by virtue of her being a king's daughter. So is it with the soul. If it were to be brought all the delights of the world, they would be as nothing to it.”
