How I am viewing things is that metta cultivates a more habitual sense of loving-kindness for others and oneself. And is therefore also great for mediating anger and ill will, which supports our practice, let’s say we are open and less aversive towards reality partially because of metta. And quite similar because of generosity(which metta is a form of, giving away our thoughts and attention ) we become familiarised with letting go, this also supports out practice.
However, there seems to be an idea that by sending wishes or radiating loving-kindness towards others this may literally change their experience to a more positive one. This is an entirely different approach initially although the outcome/action is the same . One focused on benefits for inclination of mind and the other focused on helping others.
My question, is there any point in helping out of this intent to change someones situation? Let’s say someone is feeling sad, would we want to change their predicaments if feeling is just feeling? I can’t grasp why someone who fully comprehends this would help.
