First prepare a clean bowl, a marker, a lighter and some champhor.
Go to an empty room, please be reminded that you must be alone.
Now. Set your alarm clock to 12 midnight.
Wake up instantly upon the alarm sounds.
When you are awake, do not think of anything, start marking the inside brim of the bowl numbers 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0 as shown below:
Fill the bowl with water until the level of the numbers.
Perform a short meditation then predict a number combination that you think will come out at a particular date.
Burn a piece of camphor and put it on the surface of the water, observe what number the camphor is moving to. Repeat until you have got all the numbers.
For a starter, perform the ritual and test if your number will come out. You might need to do this for a few times.
Once you got the hang of it, start your bidding...
But still, as a friendly advise, do not be greedy; small gamble is good, big gamble will make you bankrupt.
I am not responsible on whatever the consequences if you really put this into practice.
