The humble sage, by virtue of true knowledge, sees with equal vision a learned and gentle brahmana, a cow, an elephant, a dog and a dog-eater [outcaste]. (Bg. 5.18) On the spiritual platform, the learned person not only gives up the duality of man and woman, but also gives up the duality of man and animal. This is the test of self-realization. One must realize perfectly that the living being is spirit soul but is tasting various types of material bodies. One may theoretically understand this, but when one has practical realization, then he actually becomes a pandita, one who knows. Until that time, the duality continues, and the conception of man and woman also continues. In this stage, one should be extremely careful about mixing with women. No one should think himself perfect and forget the sastric instruction that one should be very careful about associating even with his daughter, mother or sister, not to speak of other women. Srila Madhvacarya cites the following slokas in this regard:

Unity in variety is real knowledge, and therefore giving up variety artificially does not reflect perfect knowledge of monism. According to the acintya-bhedabheda philosophy of Sri Caitanya Mahaprabhu, there are varieties, but all of them constitute one unit. Such knowledge is knowledge of perfect oneness.
