"We cannot jump over the highest authority directly. That is not possible. That is not the etiquette or rules, regulations we have to go. Caitanya Mahāprabhu says, gopī-bhartuḥ pada-kamalayor dāsa-dāsānudāsaḥ (CC Madhya 13.80). So He presents Himself as the servant of the servant of the servant of the servant of Kṛṣṇa. So in order to become Kṛṣṇa's servant, we have to become the servant of the servant of Kṛṣṇa. So, my Guru Mahārāja is servant of Kṛṣṇa, his guru, his guru is servant of Kṛṣṇa, his guru is servant of Kṛṣṇa. I am also servant of Kṛṣṇa, but I have to approach through the other servants, not directly. That is not possible. Kṛṣṇa will not accept that service. If one disrespects the paramparā system, then he'll not be accepted by Kṛṣṇa."
