This decision was deeply influenced by the philosophy of Brahmacharya — spiritual and practical purity — largely associated with celibacy and asceticism. Gandhi saw Brahmacharya as a means of becoming close with God and as a primary foundation for self realisation. In his autobiography he tells of his battle against lustful urges and fits of jealousy with his childhood bride, Kasturba. He felt it his personal obligation to remain celibate so that he could learn to love, rather than lust. For Gandhi, Brahmacharya meant "control of the senses in thought, word and deed.".[79]
Towards the end of his life, it became public knowledge that Gandhi had been sharing his bed for a number of years with young women.[80][81] He explained that he did this for bodily warmth at night and termed his actions as "nature cure". Later in his life he started experimenting with brahmacharya in order to test his self control. His letter to Birla in April, 1945 referring to 'women or girls who have been naked with me' indicates that several women were part of his experiments.[82] He wrote five editorials in Harijan discussing the practice of brahmacharya.[83]
As part of these experiments, he initially slept with his women associates in the same room but at a distance. Afterwards he started to lie in the same bed with his women disciples and later took to sleeping naked alongside them.[82]
