It's every practitioner's dream to integrate the spiritual practice into his or her daily endeavors. Just for fun, I have post a mystical life story of one of the eight-four siddhas lived in the eighth to eleventh centuries India - Tandhepa, 'the Dice-player.' Translated from Tibetan version by James B. Robinson in the book "Buddha's Lions." Just beware of the cultural gap and the meaning of certain Buddhism terms such as "empty" should not be taken literally as "nothing", i.e. emptiness is NOT nothingness.
"Tandhepa, 'the Dice-player', was a person of low caste in the land of Kausambi. Having exhausted all of his wealth by continuously playing dice, he was soon penniless. He continued to compulsively play dice, but since he had lost all of his money, everyone avoided him. He became so dejected that he went to a cemetery and remained there.
A yogin came along and said to him, "What are you doing here?" Tandhepa replied, " I love to play dice, but I have lost my entire fortune. Both my body and mind are tormented, and so I am staying here." The yogin then asked him, "Would the Dharma be of use to you?" To which Tandhepa replied, "I cannot give up dice-playing. But if there is a teaching which would not make me give it up, then I could use it." "There is such a one," said the yogin, and he gave him initiations and instructions:
"Meditate on the three worlds being emptied just as your purse is emptied when you play dice. Meditate on the mind itself being empty, as empty as the three worlds."
Just as you can get rid of a fortune at dice,
you can get rid of conceptions by the dice of knowledge.
You should pound the conceptions into the Dharma-body
just as you are now pounding on yourself.
Just as surely as you sleep in this cemetery,
you will rest in great joy.
Tandhepa meditated according to the way he was taught, dissolving the conceptualizations of the three worlds into the Dharma-nature. In this way, he acquired the knowledge arising from the clear understanding that everything is without self-nature. Having obtained the fruit of Mahamudra, he said:
If at first distress did not arise,
then how could I enter the path of liberation?
If I had not taken recourse to my guru with faith,
how would I have entered the highest siddhi?
After he had spoken, he rose in the sky, and in that very body, he went to the realm of Dakas."
