Contemplation: Untouched by Conditions

After reviewing the guidelines for practice, take this as your object of contemplation:

When you remain entirely untouched by conditions, whether or not they are present in combination, you bring to an end all the causes of coming into being and ceasing to be.  At that moment, you will awake to perfect enlightenment, which is your true nature and which neither comes into being nor ceases to be.  It is the pure, fundamental mind, the fundamental, everlasting enlightenment.
