Verses 10-12 of 27 Verses on Mind Training

10) To avoid decisively this disastrous way of hatred, bring to birth within your stream of awareness the maternal mind of totally positive intentions toward all beings as toward cherished children. This mind of kindness, supremely skillful in loving care, unveils the infinite value of every single life, demonstrating compassion as the meaning of existence. But the clumsy negative mind, operating blindly without concern for the preciousness of others, drains the nectar of meaning from human life. Cultivate diligently the selfless love that transforms every thought and action into tangible help for conscious beings.  

11) The method taught by awakened sages to develop this skillful mind of kindness is to cut the root of all selfish projections by repeatedly and intensively studying Perfect Wisdom, meditating single pointedly on its essence in a state of contemplative stillness and stability. With the clarity and honesty of such concentration, projected worlds of self-serving desire will melt in the sunlight of meditation, like structures of ice, revealing the magnificent secret of our existence, its total significance and absolute justification, which is active compassion for all conscious life.  

12) Such meditative practice brings to light the mind which envisions only the well-being of others, which is constantly grateful to all beloved beings for the immeasurable kindness they have poured forth through beginningless time as mothers, fathers, children, friends, benefactors, and teachers. This mind of goodness knows only the ceaseless longing to benefit all these blessed beings without exception in whatever manner and on whatever level imaginable.
