One should pray facing the wall. One's bed shouold be facing North to South. One who finishes praying earlier, should not leave a friend behind. Is this the case in every situation? Evil spirits (which may just mean anxieties) are all around us. What is the best way to deal with it? Best to pray in a synagogue. If ten people pray together, three people judge together and two (or even one) people learn together, the presence of God is there. God wears (figuratively) tefillin. Just as we declare the God is one, God declares that we are the chosen one. Best to choose a place and always pray there. One should not run away from the synagogue. One gets rewarded for running to learn, for crowing on to hear a shiur, for delving into the text, for being silent in the house of a mourner, for giving charity on a fast day, for praising a bride and groom. One cannot pray while facing a different direction from everyone else. One should be careful always to pray the mincha service (and all the others). One must make the bride and groom happy at their wedding.
