Although we all have a fundamentally pure nature, it is not easy to get in touch with it. The gross way our mind originally functions drowns out this deeper, more subtle vibration to such an extent that we generally remain unaware of its existence. If we truly want to connect with this subtle essence, we need to quiet all distractions and loosen the hold our ordinary appearances and conceptions have on us.

~ Lama Thubten Yeshe, Introduction to Tantra
