The individual who desires to receive a human birth in his next life earnestly and diligently makes effort and does not waste even a single moment unnecessarily. For those who don’t have faith in this ideal, they become careless, negligent and oblivious.
Ask your own self, “How many hours did I spend in practicing devotion?” You devoted ten times as much time to study for a bachelors and masters degree to satisfy your desires. How many hours did you dedicate for your spiritual goal? Yet, you expect to receive full and complete benefit.
The degree of aspiration to receive a human birth should also warrant the same degree of endeavor.
