It is easier to gain mastery in the wilderness, away from all temptations, but the mastery that you gain in the world is of much more value. The former can be upset by a slight stroke, while the latter, achieved in the crowd, will last forever. It is very difficult. When you are thinking of God, someone comes and says, "You did not come to my birthday party yesterday. That was very bad. Now tomorrow there is the wedding of my brother, and you must come." Now you are wanting to think of God, and the thought comes, "What present could I take?" You are sitting in your meditation, and someone comes and says, "You must come to the dinner at the club. Many interesting people will be there, and you must come."
