If there are errors in other religions, that is none of our business. God, to whom the world belongs, takes care of that. - Ramakrishna

You see many stars in the sky at night, but not when the sun rises. Can you therefore say that there are no stars in the heavens during the day? O man, because you cannot find God in the days of your ignorance, say not that there is no God. (Sutra 1)

God can be realized through all paths. All religions are true. The important thing is to reach the roof. You can reach it by stone stairs or by wooden stairs or by bamboo steps or by a rope. You can also climb up by a bamboo pole.

He is born in vain, who having attained the human birth, so difficult to get, does not attempt to realise God in this very life. (2)
