The impersonalist who prefers to merge with the Brahman effulgence has no shelter at the lotus feet of Krishna. Therefore such impersonalist even though raised to the Brahman platform come down again to the material world for pleasure's sake. In India you will find many sannyasis who merge into the Brahma effulgence, but without any pleasure there, they come down to the platform of material activities of opening schools and hospitals - Daridra Narayana, etc. Such men with poor fund of knowledge do not know that in the material world however you try to arrange things very right, it will always fail. But in the spiritual world the spiritual varieties displayed by Krishna along with his associates gives eternal pleasure. That is wanted. The Brahma effulgence, there the pleasure is temporary.
