Losar is the Tibetan New Year. It is known as merit-increasing, so that if you practice meritorious activities during these days around the new year, this year Feb. 19th, then your overall positive accomplishments will be increased. I've dedicated myself to meritorious activities during these days, reciting prayers for Lama Zopa Rinpoche (pictured below practicing empowerment of Tara for practitioners) and increasing my time spent meditating and practicing Reiki and voodoo prayers for others and myself (whoops maybe I should only do for others, jk jk).
