Mudita.
Mudita is something, like all Brahmaviharas, that needs to start by oneself. Given the topic, althought such accounts are often not beloved as they easy could seem as a doing a favor, it is because of one's many sacrifices in the past, one's merits done, past and present, that such as this so seldom relation and tendency toward Buddha, his Dhamma, his Sangha, has been gained.
That's not just easy talked, but can be "easy" observed. So far appart, living in areas of grave wrong view, far away from the traditions and absence of Dhamma, and yet able to enter a dhammic forest and leave home. If thinking right that is not at all a reason for sadness and Nyom
Cheav Villa and others, living relative near physical, will possible confirm that such is wealth 1 under 10.000 even in a traditional country.
Only one who knows "his" wealth, knows the worth of it, is not only be able to recognize wealth of others but also to rejoice with it, appreciate it. And in this way ones real wealth increases.
Balance, equanimity, is something that develops by itself, based on faith (acting according the Dhamma), no will required.
Maybe Nyom
angela tries to climb up this Sublime Dwelling of Mudita and rejoice by sharing her merits seen here with all beings, starting by her parents and supporter down to those now in more bad states and up to the highest Gods and those on the path.
Dwelling in gratitude with the Brahmas, starting by ones parents, is actually already a borderland to the Noble Domain, relation.
Dwelling there often while having certain touch by the Juwels, seeking refuge in the Juwels, it's possible to leave home and stand, once left, possible to hear and see the Dhamma and sure of change in relation on that, relation that is destinated to freedom from suffering, Unbound.
(Needed basics, such as the powerful mudita, sharing merits, appreciating them is as good as unknow in moder/western world, no trader in Dhamma would ever be able toteach it. Maybe some ideas on it
