Preaching without practicing is nothing but a ritual of karma-kanda.
Prabhupada says, “speak what i have said. This is preaching. You are not the preacher. I am the preacher. You simply repeat my words”.
Those who are preaching, they have to take risk. Sometimes they will be hurt, harassed, humiliated but that’s why they are in the heart of the Lord. In this movement everyone has to be a preacher.
It is easy to become a monk without Lakshmi, but not to preach.
The nectar of Krishna's words and the descriptions of His activities are the life and soul of those suffering in this material world. These narrations, transmitted by learned sages, eradicate one's sinful reactions and bestow good fortune upon whoever hears them. These narrations are broadcast all over the world and are filled with spiritual power. Certainly those who spread the message of Godhead are most munificent.
At a time when demoniac influence is so prevalent everywhere, to preach love of God is not so easy. However the devotees of ISKCON are pushing on with this mission with absolute determination and dedication.
