"Vasettha, all of you, through of different birth, name, clan and family, who have gone forth from the household life into homelessness, if you are asked who you are, should reply: 'We are ascetics, followers of the Sakyan.' He whose faith in the Tathagata is settled, rooted, established, solid, unshakeable by any ascetic or Brahmin, any deva or mara or Brahma or anyone in the world, can truly say: 'I am a true son of Blessed Lord, born of his mouth, born of Dhamma, created by Dhamma, an heir of Dhamma.' Why is that? Because, Vasettha, this designates the Tathagata: 'The body of Dhamma', that is, 'The body of Brahma', or 'Become Dhamma', that is, 'Become Brahma'.
"Do not block your six senses; delight in them with joy and ease.
All that you take pleasure in will strengthen the awakened state.
With such a confidence, empowered by the regal state of natural mind,
The training now is simply this: lets your six senses be at ease and free." - Princess Parani
