This one sentence for me is the meaning behind this. "When you have to accomplish a particular purpose, the main thing is that you have to take things in hand."
Somewhere and somehow, many folks seem to miss the need to take personal responsibility for themselves. You can see this when you notice all the "get rich quick" schemes running rampant on the internet.
Everything we do requires that we "take things in hand" that is, take personal responsibility for. This allows each of us to know that we can accomplish anything we desire when we take things in hand, and take action to accomplish our desires.
