He had His very beautiful and obedient wife, Lakṣmī devi, sixteen years old. She was by name Lakṣmī, and actually she was goddess of fortune . . . and His mother was so affectionate, there is no comparison. So in a home where mother is . . . affectionate mother is present, and very beloved wife is present, and at the very young age . . . He was twenty-four years old, and His wife was sixteen years old. Materially that is the age for sense gratification, but He renounced. He didn't care for His wife, didn't care for His mother.
So renunciation is also one of the opulences, and it is described in the Śrīmad-Bhāgavatam about His renunciation, tyaktvā sudustyaja-surepsita rājya-lakṣmīṁ (SB 11.5.34). Su-dustajya. Su-dus . . . Tyaja means give up, and du means difficult, difficult, and su means very difficult. In any word, if you apply, affix the word su, it becomes hundred times more magnified. Just like buddhi. Buddhi is intelligence, and if you affix subuddhi, that means very, very intelligent. Similarly dustyaja, "difficult to give up," and when you affix this alphabet su, it becomes "very, very, very difficult." So su-dustyaja, this word, has been used.
