1. First one must control the tongue

    …because of the greed for tongue the whole world is going on; all the work in the world is going on because of the greed for the tongue. Some places have restaurant, some have tea, somewhere bidis, somewhere cigarettes, somewhere there is meat eating and intoxication and what is there, this tongue, everything is because of this tongue. If you can control your tongue and engage it in God's service, then you can see God. This is the instruction in the scriptures. First one must control the tongue.
