Based on Geshe-la's advice, Gen-la Dekyong has been encouraging us to make mandala offerings every day with a mandala kit, because it will help us quickly gain realizations.
At Summer Festival last year, she also suggested everyone bring their kit with them to the Portugal Festival, because it would be a wonderful offering to Geshe-la. (She said we could take out our large bottle or conditioner or our fancy shoes to make room for the kit.)
If you don't know how to make offerings with a mandala kit, you can ask your Sangha.
In Seattle we have a Guru Yoga and Mandala Offerings Retreat this Saturday through the following Thursday at KMC Washington. If you'd like to learn, I'm sure there will be someone who is happy to teach you, especially if you arrive a bit early. Note that we have some new meditation classes, so there won't be retreat sessions at the Temple during those times.
