Krsna is dear to his devotees because of reciprocation. The verse Ye yatha mam prapadyante tam tathaiva bhajamy aham, Bg.4.11., is further deepened by Sanatan Goswami in his Dig Darsini, where he writes: “and He (Lord Krsna) would follow Yudhisthira in procession and offer words of praise like an ordinary subordinate.” (translation by Gopiparanadara of the Dig Darsini purport, Sri Brhad Bhagamarta p.344)
