Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura says that the mellow of neutrality increases to simple love of Godhead. In the mellow of servitorship, love of Godhead increases beyond that to affection, counter-love (anger based on love), love and attachment. Similarly, the mellow of friendship increases to affection, counter-love, love, attachment and subattachment. It is the same with the mellow of paternal affection. The special feature of the mellow of friendship exhibited by personalities like Subala is that it increases from fraternal affection to counter-love, to spontaneous attachment, to subordinate attachment, and finally to the ecstasy where all the ecstatic symptoms continuously exist.
