न चागमादृते धर्मस्तर्केण व्यवतिष्ठते ।
ऋषीणामपि यज्ज्ञानं तदप्यागमपूर्वकम् ॥
Rituals are an integral way of following dharma. One can not establish dharma in a society based solely on logic. Even the ancient sages who started these rituals knew about this. All their knowledge (about the universe) is hence not opposed to the rituals that they began.
