यज्ञफल - अनुभव

अनुभवेन विनाधिगतं श्रुतं
    भवति नैव नॄणामुपकारकं ।
दधिनि वतर्त एव हविः पुनः
    न मथनेन विना विना तदवाप्यते ॥

- यज्ञफल

All the knowledge that one may learn from others, or read in scriptures is of no use unless one ratifies them by experience. Curd does have ingredients of ghee - but it still requires a lot of processing.
