This is Kawaguchi Hidetoshi. This is my humble answer to the question.
Instead of forcibly “loving and falling in love with yourself” or “affirming yourself,” try “showing mercy to yourself.”
In “Mercy Meditation,” first of all,
“May I be happy
May my worries and suffering go away
May my wishes come true
May the light of enlightenment appear in me
May I be happy”
I'll start by multiplying mercy on myself, and the reason for this is that in order to save others, you must first be saved yourself.
Even though you haven't been saved, you can't save anyone else.
Even though you don't have any money, it's like you can't lend anything else.
Also, in Buddhism, the object to be saved is all sentient (sentient beings), and of course, oneself must also be included there.
In a sense, it's similar to loving yourself in order to love everything.
However, in a sense, “loving” can also be unfavorable because it involves one's own complacency and selfishness.
Rather than that, if it is “mercy,” I think you will be able to have a positive heart and a bright heart for yourself by cultivating equal love that is not someone specific.
Please think about it once.
As for meditation on mercy, I think one from the Japan Therawada Buddhist Association may be helpful.
