Śrīmad-Bhāgavatam Sat 23rd July 2016 - As the Supreme Personality of Godhead can expand Himself in millions of forms, a yogī can also expand up to nine forms, but not more than that. But however powerful a yogī may be, he cannot expand himself into more than eight or nine forms. The Supreme Personality of Godhead, however, can expand Himself into millions of forms.
