The buddha has said that our main task is to accumulate the two, wisdom and merit. The Eight Offerings is an ancient tradition to invite or welcome a Buddha or a Boddhisattava into ones home or into ones practice through meditation. Just by making the eight offerings everyday on your shrine or when you use it in your daily practice it has immense benefit without us even realising it. When we make the offering everyday it reminds us to stay vigilant to our enlightenment goal, it disciplines the mind and since it is an act of generosity we accumulate merit through the offerings.
