Question: I understand that filial piety is very important in Buddhism. However, I’m estranged from my family. As my parents treat me as non-existent, I rarely contact them. As staying with them caused them suffering, I chose to move out. They even told me not to bother coming to their funerals. As such, filial piety no longer exist in my mind. Is it possible to be liberated or born in Pure Land without practising filial piety then? I might seem heartless but it was against my will that my parents chose to ‘disown’ me.
Answer: Filial piety is seen as the most basic form of gratitude, as you can see at https://thedailyenlightenment.com/2010/01/what-basic-integrity-gratitude-should-we-have (What Basic Integrity & Gratitude Should We Have?) Hmmm… Did you do something to make your parents unhappy? If so, have you apologised verbally and with actual remedial actions? Or was there some misunderstanding? If so, have you discussed with them sincerely and calmly on the matter? You can also do more good deeds and dedicate the merits for your reconciliation.
We have to do our best to resolve negative karmic affinities and to transform them to be positive. Only after you have tried your best to reconcile, and that it is totally hopeless (Is is ever so?), is it alright to let go for the moment, till conditions improve later. If not, there might be strong negative karma hampering good Dharma practice, or regrets on your deathbed that distract good practice. That this problem affects you enough to ask about it is already proof of it being a spiritual obstacle disturbing you to some extent. As you used inverted commas for ‘disown’, I guess they didn’t really disown you. There is hope then? Please don’t disown hope.
