four kindnesses of the mother
In the seven points of cause and effect technique for developing bodhicitta, the second, remembering the kindness of the mother, can include how the mother has been kind in four ways: 1) the kindness of giving her body; 2) the kindness of protecting our life from danger; 3) the kindness of bearing hardship; and 4) the kindness of leading us in the ways of the world. The lineage of this came to Lama Zopa Rinpoche from Khunu Lama Tenzin Gyaltsen Rinpoche.
