Lama Zopa Rinpoche advises that the stupa should be placed in the kitchen, living room, or on a table. By simply looking at the stupa, there is empowering purification that brings you to enlightenment. The stupa purifies negative karma collected from the beginning of your life that are obstacles to temporary and ultimate happiness.
If you have pets, such as dogs and cats, you can also bring them around the stupa by holding them in your hands, so they are at the same level as the stupa.
When you go around the stupa, recite OM MANI PADME HUM or other mantras.
