Real business is preaching work, and if there is full attention on this matter only, all other businesses will be automatically successful. Fighting amongst ourselves is not at all good, but if our preaching work is neglected, or if we fall down in following the regulative principles such as rising before four, chanting 16 rounds, like that, if these things are not strictly observed then maya will enter and spoil everything. So my best advice to you is to strictly observe these things yourself and be the example so that all others may follow.
