“The only medicine for suffering, crime, and all the other woes of mankind, is wisdom.”

Context: Those who criticised me didn't know Modi is such a magician who also made them speak on important agendas. But all these discussions also told the country that only development can save the country. Even if they spoke about Gujarat negatively, they still spoke about development. There is only one medicine to all problems—development.

Freeman (1948), p. 149
Variant: Medicine cures the diseases of the body; wisdom, on the other hand, relieves the soul of its sufferings.

Context: Masonry will do all in its power, by direct exertion and co-operation, to improve and inform as well as to protect the people; to better their physical condition, relieve their miseries, supply their wants, and minister to their necessities. Let every Mason in this, good work do all that may be in his power.
For it is true now, as it always was and always will be, that to be free is the same thing as to be pious, to be wise, to be temperate and just, to be frugal and abstinent, and to be magnanimous and brave; and to be the opposite of all these is the same as to be a slave. And it usually happens, by the appointment, and, as it were, retributive justice of the Deity, that that people which cannot govern themselves, and moderate their passions, but crouch under the slavery of their lusts and vices, are delivered up to the sway of those whom they abhor, and made to submit to an involuntary servitude.
And it is also sanctioned by the dictates of justice and by the constitution of Nature, that he who, from the imbecility or derangement of his intellect, is incapable of governing himself, should, like a minor, be committed to the government of another.
Above all things let us never forget that mankind constitutes one great brotherhood; all born to encounter suffering and sorrow, and therefore bound to sympathize with each other.
For no tower of Pride was ever yet high enough to lift its possessor above the trials and fears and frailties of humanity. No human hand ever built the wall, nor ever shall, that will keep out affliction, pain, and infirmity. Sickness and sorrow, trouble and death, are dispensations that level everything. They know none, high nor low. The chief wants of life, the great and grave necessities of the human soul, give exemption to none.

Context: Lo these were they, whose souls the Furies steel'd,
And curs'd with hearts unknowing how to yield.
Thus unlamented pass the proud away,
The gaze of fools, and pageant of a day!
So perish all, whose breast ne'er learn'd to glow
For others' good, or melt at others' woe.
