The Buddha says that clarity about what is "wholesome" and what is unwholesome" is important. We are encouraged to cultivate qualities like Metta (loving kindness) for our own benefit and that of others.
Cultivate the quality of intention rather than objects of attention. Intention is broader, it encompasses everything. Correct intention neither holds on, nor resists. The quality of anukampā – primary sympathy – from which mettā arises. Puja acts as an emblem, it resonates meanings that open the heart. Beyond the physical body or personal state, rise up to the sign of the beautiful, worthy, admirable and the good.
From my teacher Thea Elijah, through establishing our connection to the earth, we create common ground upon which we realize our interconnectedness. This meditation guides us through this process so that we can offer lovingkindness to ourselves, a beloved, a neutral person, a difficult person, and all beings.
