On 4 August 1904, at age 36, she married Philippe Neél de Saint-Sauveur, whose lover she had been since 15 September 1900. Their life together was sometimes turbulent but characterized by mutual respect. It was interrupted by her departure, alone, for her third trip to India (1911–1925) (the second one was carried out for a singing tour) on 9 August 1911. She did not want children, aware that motherhood was incompatible with her need of independence and her inclination to education. She promised to return to Philippe in nineteen months, but it was fourteen years later, in May 1925, when they met again, separating after some days. David-Néel had come back with her exploration partner, the young Lama Aphur Yongden, whom she would make her adopted son in 1929.
