Life is short and the time of death is uncertain; so apply yourself to meditation. Avoid doing evil, and acquire merit, to the best of your ability, even at the cost of life itself. In short: Act so that you have no cause to be ashamed of yourselves and hold fast to this rule.
MilarepaWhen you run after your thoughts, you are like a dog chasing a stick: every time a stick is thrown, you run after it. Instead, be like a lion who, rather than chasing after the stick, turns to face the thrower. One only throws a stick at a lion once.
MilarepaAll worldly pursuits have but one unavoidable and inevitable end, which is sorrow; acquisitions end in dispersion; buildings in destruction; meetings in separation; births in death. Knowing this, one should, from the very first, renounce acquisitions and storing-up, and building, and meeting; and, faithful to the commands of an eminent Guru, set about realizing the Truth. That alone is the best of religious observances.
