Parting from the Four Attachments - His Holiness Sakya Trizin - Bog

This teaching, the path of all Buddhas of the past and of the future
that contains all the deep meanings of all the Sutras combined in a
practical way, is known as the Mind Training or Pith Instructions,
presented by the great masters in the most practical way through
their own experience. The history of this teaching is this. When
the great Lama Sakyapa was twelve years old, his spiritual master
suggested that since he was the son of a great spiritual master he
should study the teaching; however, in order to study the teaching
he needed first to acquire wisdom. In order to acquire wisdom, he
had to practise Manjushri, the manifestation of all the Buddhas'
wisdom. Sakyapa's spiritual master, Pari Lotsawa, one of the greatest
translators, gave him the initiation of Manjushri and all the
teachings related to Manjushri and then asked his disciple to do
a meditation retreat. After completing six months of meditation,
one day in his pure vision he saw Manjushri in person sitting on a
jewel throne, his hands in the teaching mudra, with two Bodhisattva
attendants, one on each side. Then the main deity Manjushri
gave this teaching, which is made up of four lines:

If you have attachment to this life, you are not a religious person.
If you have attachment to the world of existence, you do not have
renunciation.
If you have attachment to your own purpose, you have no Enlightenment
Thought (Bodhicitta).
If grasping arises, you do not have the view.

All the paths of the Sutrayana are included in these four lines.
