“Freedom from activity is never achieved by abstaining from action. Nobody can become perfect by merely ceasing to act. In fact, nobody can ever rest from his activity even for a moment. All are helplessly forced to act. . . .
A man who renounces certain physical actions but still lets his mind dwell on the objects of his sensual desire, is deceiving himself. He can only be called a hypocrite. The truly admirable man controls his senses by the power of his will. All his actions will be disinterested.
Activity is better than inertia. Act, but with self-control. If you are lazy, you cannot even sustain your own body.”
― Anonymous, BHAGAVAD GITA: EL CANTO DEL SEÑOR

“The nonpermanent appearance of happiness and distress, and their disappearance in due course, are like the appearance and disappearance of winter and summer seasons.They arise from sense perception,and one must learn to tolerate them without being disturbed.”
― Anonymous, The Bhagavad Gita

“Anyone who is steady in his determination for the advanced stage of spiritual realization and can equally tolerate the onslaughts of distress and happiness is certainly a person eligible for liberation.”
― A.C. Bhaktivedanta Swami Prabhupada, The Bhagavad-gita

“The happiness which comes from long practice, which leads to the end of suffering, which at first is like poison, but at last like nectar - this kind of happiness arises from the serenity of one's own mind.”
― Ved Vyasa, The Bhagavad Gita
