Mahatma Gandhi used say that 'Truth is God and God is Truth'.If a person is truthful in all his action,he can realize God even if he does not pray to god.His devotion to truth takes him to god.the word truth means that which exist'.Falsehood has no existence,only truth exist.If we think deeply we can see that god alone exists.god is the only reality.Other things are not real Only those things that exist for ever are real
