Sachen Kunga Nyingpo (as spoken to him by Manjushri) (1092-1158)

If you are in love with this life, you are not a true spiritual practitioner.

If you are in love with samsara, you do not have renunciation.

If you are in love with your own benefit, you have no bodhichitta.

If you have the mental factor "in love" , you do not have the View.

(as translated by Dzongsar Khyentse Rinpoche, Kathmandu 2009)
