The Lama Chopa or "Guru Puja" is a practice that incorporates all of the most essential teachings of the Buddha--everything required to achieve Enlightenment.
We usually see ourselves as ordinary people in a polluted environment, surrounded by so many problems and so much suffering and ignorance.
During the Lama Chopa, we actively cultivate a different world view-- an Enlightened perspective. We imagine what it would be like to be an Enlightened being or a Buddha, seated in a Buddhaverse in a sky filled with Enlightened teachers. And, then we visualize around us all of the countless unenlightened beings who are suffering.
We then develop great compassion for all beings' suffering and engage in practices so as to liberate all suffering beings, leading them and ourselves to Enlightenment.
Doing these practices in relation to our spiritual teachers or mentors with a motivation of deep compassion for all suffering beings is said to be the fastest, most effective way of progressing towards Enligthenment ourselves in order to benefit others.
The Guru Puja is often combined with the offering of Tsog. Through the power of our motivation, prayer and actions, we transform offered food and flowers into precious substances with the power to bestow blessings of infinite value. This special prayer feast creates merit and honors the Merit Field of Holy Beings. All who take bodhisattva vows commit to make offerings as often as possible. Those who take a highest yoga tantra empowerment commit to offer Tsog on the tenth and twenty-fifth of each Tibetan lunar month. This practice strengthens one's commitment to the Guru and helps to purify any infractions. Making a tsog offering as part of Guru Puja is the perfect way to honor these commitments.
