“If you are attached to this life, you are not a dharma practitioner.
If you are attached to samsara, you don’t have renunciation.
If you are attached to selfish aims, you don’t have bodhicitta.
If you are attached to grasping, you don’t have the view”.
Sachen Kunga Nyingpo (1092-1158), Founder of the Sakya Lineage.
When Kunga Nyingpo was twelve, his root master advised him to practice Manjushri in order to attain prajna. After practising for six months he had a vision of Manjushri surrounded by bodhisattvas. Manjushri then spoke these words to Sachen Kunga Nyingpo.
From: The Song of Experience by Jetsun Drakpa Gyaltsen (1147-1216), son of the Kunga Nyingpo, composed from the root text, Parting from the Four Attachments.
