Field of Merit
This image depicts the Lamrim Field of Merit as described in the book Joyful Path of Good Fortune.
Buddha Shakyamuni is in the centre, surrounded by a vast assembly of holy beings, including Buddhas, Bodhisattvas, and all the lineage Spiritual Guides of Sutra and Tantra.
They are called a "Field of Merit" because by developing faith and making prayers and offerings to this assembly of holy beings, we create a vast amount of merit, or good karma, which prepares our mind for successful Lamrim (stages of the path) meditation.
This picture depicts the main visualization for Offering to the Spiritual Guide, which is a special spiritual practice of Je Tsongkhapa's tradition, done twice a month at all Kadampa Buddhist Centers.
The main practice is relying upon the Spiritual Guide, but it also includes the essence of all the stages of the path (Lamrim) and training the mind (Lojong), as well as all the Tantric practices.
