So besides the standard brahma-viharas: loving-kindness, compassion, appreciative joy and equanimity;
I have been making a list of words that can be combined to create custom positive affirmations.
mix and match however you wish and try to visualize and create an emotional response. I mix in deity practice with green tara as this giant protective being holding me and then I hold my little self and mix the perspectives around as I say positive things to myself. I recieve and give. The right brain likes this stuff and takes it in even though the logic left side is critical at first. I internalize the feeling tones of loving myself with kindness and creating a new subconscious process of being a perfect being that supplies myself with limitless love for all my inner children age groups up to adult. (try some on your loved ones too)
Feel free to post more words if you have some good ones.
Good luck,
~D
