Krsna shows that ultimately, higher even than dharma (duty), is the love that exists between Krsna and his devotee. That is why in Kurukshetra, Krsna broke his vow. Krsna had promised not to fight, but when Bhismadev was about to kill Arjuna, suddenly he took up the wheel! Just see!
Krsna shows that the love for his devotee is even greater than dharma. That’s even greater – the loving relationship that exists between the devotee and Krsna and it is that very secret that Sri Caitanya Mahaprabhu came to teach.
