In meditation you withdraw from others and focus your attention inside to gain purity of mind and wisdom energy. Then you must become extroverted and use this energy. When you take a long jump, you must first take some steps backward. Then you run, and make the jump. Like this, you first withdraw, observe yourself, develop clarity and unlock the wisdom. Then you make a long jump into society, to serve society. These two steps cannot be separated.
