M.k Gandhi said this quote

“ I realized that in refusing to take a vow man was drawn into temptation, and that to be bound by a vow was like a passage from libertinism to a real monogamous marriage. 'I believe in effort, I do not want to bind myself with vows' is the mentality of weakness and betrays a subtle desire for the thing to be avoided. Or where can be the difficulty in making a final decision? I vow to flee from the serpent which I know will bite me, I do not simply make an effort to flee from him. I know that mere effort may mean certain death. Mere effort means ignorance of the certain fact that the serpent is bound to kill me. The fact, therefore, that I could rest content with an effort only means that I have not yet clearly realized the necessity of definite action. 'But supposing my views are changed in the future, how can I bind myself by a vow?' Such a doubt often deters us. But that doubt also betrays a lack of clear perception that a particular thing must be renounced. That is why Nishkulanand has sung: 'Renunciaton without aversion is not lasting.' Where therefore the desire is gone, a vow of renunciation is the natural and inevitable fruit. ”
