You shall always hold classes. Read these books, discuss, try to understand. Then time will be properly utilized. Don’t talk useless things. Some engagement. So long you are engaged in service of the Deity, that is very good. Otherwise, you should hold class, read these books, discuss among them. Then the proper utilization of time. Avyartha-kalatvam [Cc. Madhya 23.18]. Advancement of devotional service means always be alert whether a moment is misused. Because you cannot get back even a moment of your life if you pay millions of dollars. Not possible. Nineteen sixty-seven, 10th June, 5 o’clock, you had to do something, and if you have missed, then that 5 o’clock, 10th June, 1960, ah, ’76, will never come back, even you pay millions of dollars. So if that moment is improperly passed, then what is more loss than that? So avyartha-kalatvam. We should not let even a moment of our life misused. Avyartha-kalatvam. Nama-gane sada rucih. This is advanced life of Krsna consciousness.
