Srila Visvanatha Cakravarti Thakura explains that this superficial appearance of insanity in Lord Krishna's queens, as if they had become intoxicated by dhattura or some other hallucinogenic drug, was in fact the manifestation of the sixth progressive stage of pure love of Godhead, technically known as prema-vaicitrya. Srila Rupa Gosvami refers to this variety of anuraga in his Ujjvala-nilamani (15.134):
priyasya sannikarshe 'pi
premotkarsha-svabhavatah
ya vislesha-dhiyartis tat
prema-vaicitryam ucyate
"When, as a natural by-product of one's extreme love, one feels the distress of separation even in the direct presence of the beloved, this state is called prema-vaicitrya."
