According to Tibetan Buddhism there are four days a year (date varying from year to year according to the lunar calendar) when the power of our thoughts is much stronger than on other days (10 million times stronger). February 25th is the first of these four days in 2013.
In Tibet they celebrate this day with the Butter Lamp Festival.
Here is some info from http://tibetanbuddhistinstitute.org
"To commemorate the Day of Miracles, there is an annual Butter Lamp Festival that occurs annually according to the lunar calendar, and it occurs after Losar, the Tibetan New year. Thousands of butter lamps are sculpted out of butter, and are lit for this festival.
Light plays a significant role in Buddhist symbolism, with the removal of darkness representing wisdom replacing ignorance."
