Did you practice with yesterday's exercise? What are your insights? You have a guru? good. You don't have a guru? good. More than one? also good. Do you believe everything your guru says, want to become like her confident that you will never accomplish this?
Take it from an old Chinese collection of stories, The Blue Cliff Record (Chinese: 碧巖錄; pinyin: Bìyán Lù; Japanese: 碧巌録; rōmaji: Hekiganroku; Korean: 벽암록; romaja: Byeokamrok; Vietnamese: Bích nham lục) compiled in 1125 C.E. (thats 892 years ago).

Endless commentaries you are welcome to read - they may or may not help you, or you can simply understand the text as be yourself, take care of your own stuff, don't try to explain, and above all - don't expect anybody to do your work, to be you so you can be someone else.
Can Buddha or Jesus or Barbarella or [enter your favorite idol] be your Guru? The dilemma starts with the understanding of the Guru.
