Try to follow the path of acarya process. Then life will be successful. And to become acarya is not very difficult. First of all, to become very faithful servant of your acarya, follow strictly what he says. Try to please him and spread Krsna consciousness. That's all. It is not at all difficult. Try to follow the instruction of your Guru Maharaja and spread Krsna consciousness. That is the order of Lord Caitanya.
amara ajnaya guru hana tara' ei desa
yare dekha tare kaha 'krsna'-upadesa
[Cc. Madhya 7.128]
"By following My order, you become guru." And if we strictly follow the acarya system and try our best to spread the instruction of Krsna… Yare dekha tare kaha 'krsna'-upadesa.
(From Srila Prabhupada's lecture on Sri Caitanya-caritamrta, Adi-lila 1.13 – April 6, 1975, Mayapur)
