Prabhupada: ...Vedic literature that ksatram dvijatvam ca parasparartham. They are meant for cooperation. So secular state does not mean that we should be neglectful of the spiritual progress of life. The government should be very careful that in the name of secularism people are going to, astray. No. So this is the movement that ksatram dvijatvam ca parasparartham. We are trying to cooperate with the political power, and we are trying to impart spiritual instruction. This is our attempt. And another thing is that according to our Vedic literature, there cannot be different religions. It is not possible. Because God is one. God cannot be two. "This is Hindu God, this is Muslim God," or "This is Christian God..." No. God is one. And dharma means dharmam tu saksad bhagavat-pranitam: [SB 6.3.19] "The law which is given by God, that is dharma." This is the simple definition of dharma. And at the end of Bhagavad-gita Krsna says, sarva-dharman parityajya mam ekam saranam vraja [Bg. 18.66]. That is the ultimate religion. One has to surrender to the Supreme Lord. This is religion.
