Your approaching schools and colleges is very tactful because these students are the most eligible candidates for receiving this transcendental knowledge of Krishna philosophy. Simply by repeating what I have said - first you must yourself become fully convinced of this philosophy - your preaching will meet with all success. Our philosophy has the full potency to deliver anyone from the darkest realms of ignorance to the enlightened realm of complete cognizance. The potential is there, simply you have to master the words and deliver them purely, and this will please me very much.
