A person who can control his senses fully is called vasi, or self-controlled. In this connection it is stated in the Srimad-Bhagavatam: "All the 16,000 wives of Krsna were so exquisitely beautiful that their smiling and shyness were able to captivate the minds of great demigods like Lord Siva. But still they could not even agitate the mind of Krsna, in spite of their attractive feminine behavior." Every one of the thousands of wives of Krsna was thinking that Krsna was captivated by her feminine beauty, but this was not the case. Krsna is therefore the supreme controller of the senses, and this is admitted in the Bhagavad-gita, where He is addressed as Hrsikesa-the master of the senses.
