I think Srila Prabhupada was like this. He always was clear in his speeches, letters, projects, and his day-to-day dealings with people (big, small, disciples, non-disciples). Such straightforward and consistent dealings puts people at ease and any doubt that may exist will soon dissipate. People may not agree or even understand fully our philosophy but if they see our dealings as simple and straight, then they will certainly value our words. Everyone is a leader, i think, and should take it upon themselves to practice simplicity and straightforwardness (not rude) with everyone.
