The cosmos has an influence on the mind. What can protect you from this influence is satsang, meditation, chanting. All this is like putting on an armour. An arrow was coming, but you have an armor, so it didn't really hit you. So, singing and chanting 'Om Namah Shivaya' so many times makes an armour around you and protects you from being affected by all these crazy things.
