Tara Practice

7:00pm.  Tara is the Buddhist deity of perfect love, health, and long life.  This practice is a beautiful prayer rich with visualizations in which we make offerings to White Tara and ask for her help in our daily lives.  This practice is open to beginners and advanced buddhist practitioners alike.  Just as we become more like those friends/ family members with whom we spend a lot of time, with consistent repetition of this prayer and meditation on White Tara in our daily lives, we begin to become more like her, full of love, health and long life..

Please meet at the Tara Temple. Cost: Free

Purification Puja (Sojong)

7:00pm.  This is a beautiful practice which involves reviewing our actions words and thoughts over the past 2 weeks.  We take time to regret those actions that may have hurt others around us or don’t reflect the kind of person we want to be.  We make a promise to ourselves not to engage in these actions for a period of time to allow ourselves to create new habits.  Then we rejoice in the good, kind actions we have done and set an intention for how we’d like to behave for the next two weeks.  The ceremony is followed by popcorn, conversation, and hot cocoa in the cooler months.

Please meet at the Student Center. Cost: Free
