First of all follow the orders of ācārya, and you become mature. Then it is better to become ācārya. Because we are interested in preparing ācārya, but the etiquette is, at least for the period the guru is present, one should not become ācārya. Even if he is complete he should not, because the etiquette is, if somebody comes for becoming initiated, it is the duty of such person to bring that prospective candidate to his ācārya. Not that "Now people are coming to me, so I can become ācārya." That is avamanya. Nāvamanyeta karhicit. Don't transgress this etiquette. Nāvamanyeta. That will be falldown.
Just like during the lifetime of our Guru Mahārāja, all our Godbrothers now who are acting as ācārya, they did not do so. That is not etiquette. Ācāryaṁ māṁ vijānīyāt na avaman. . . That is insult. So if you insult your ācārya, then you are finished. Yasya prasādād bhagavat-prasādo yasya aprasādāt na gatiḥ kuto 'pi - finished. If you displease your ācārya, then you are finished. Therefore it is said, Caitanya Mahāprabhu says to all the ācāryas. . . Nityānanda Prabhu, Advaita Prabhu and śrīvāsādi-gaura-bhakta-vṛnda, they are all carriers of orders of Śrī Caitanya Mahāprabhu. So try to follow the path of ācārya process. Then life will be successful.
