Over the years, I have really enjoyed and benefitted from the Tibetan Buddhist practice of Tonglen, which means "giving and taking." I’ve always appreciated the contrast in the Tonglen meditations, particularly in the meditation teacher DavidJi’s practice:

breath in stillness, exhale turbulence 
lightness, let go of heaviness 
breath in soothing, and release pain
breath in surrender and let go of resistance 
breath in acceptance and let go of judgement 
breath in forgiveness and let go of grievance 
breath in tolerance and let go of anger
breath in expansion, let go of constriction
breath in clarity, let go of confusion 
breath in peace, and release conflict 
breath in wholeness and let go of separation
breath in compassion and let go of sadness 
breath in joy and let go of suffering 
breath in ease and let go of struggle 
breath in flow and release effort
breath in love and let go of fear
breath in love and release love back out
