"May all sentient beings enjoy both happiness and the sources of happiness, and may they never meet with sorrow nor the causes of sorrow. 

In order that all living beings may attain complete buddhahood, I vow to practise the profound path of Dharma, from the beginning to the end. 

Dedicating myself for the sake of all living beings, I will practise so that all may escape from samsāra and attain enlightenment." 

(From the new book : The Path of Secret Mantra  http://www.wandel-verlag.de/en/the-path-of-secret-mantra/)
