Strength
Focus is real strength. The more consciousnesses are focused in one direction, the greater the strength. Water wears down stone.
One can have strength of body. Strong muscles. Some have bodily strength by nature, some train hard. A strong person can move heavy loads or defeat weaker ones.
One can have strength of intellect. One can have a strong intellect by nature, or train the intellect. A person strong in intellect can lead better, plan better, and see further ahead.
One can have strength of will. And reach one's goals through the whole life, no matter what obstacles appear.
And even better is to have a strong body, a strong intellect, and a strong will at the same time. But do not limit yourself to only these concepts. The human body, or any living body, is made of more parts. Energy, emotion, beauty, and many other forms, both visible and invisible. One can improve some features of the body until death. Or one can focus on the first source, the higher consciousness. That which will remain after death. That from which the other forms of the body come.
So my general message is this. First we need to develop the focus of consciousness. Focus will help develop the other things better. Other things in the widest sense of the word. Other parts of the body, planning of life, energies, strength of spirit, and in general anything.
