There is no limitation

"If you study my books very carefully, then I am sure you will find out the means for applying this Krsna Consciousness philosophy in all spheres of life. There is no limitation. Simply it requires a little common sense practicality. The main point is that Krsna is the center of all activities, whatever is going on. Whatever the activity may be, if Krsna is the center, that is all right. The details simply require a little common sense."
