Those sandpaper beings in one's life are those we feel challenge at hanging out with but whom we must love because that is the law of God and Buddhas. In many ways, Whiskey my late dog was a TOTAL sandpaper to me he was so disobedient. My mom is very much old sandpaper growing up but truly, her fertile whimsicality is wonderful. om shanti om! i am a better human beings for the fact that I got quite close to these two beings I now love unconditionally. My relationship with them was long lasting too.
