Nyom Chris and those interested,
my person find it always very useless to explain such as "Buddhism" and ways of "Buddhists" because what matters is to do the right things which would help others.
Helping ones mother and father is a natural intent of a person with integrity, and as the Buddha taught:
"I tell you, monks, there are two people who are not easy to repay. Which two? Your mother & father. Even if you were to carry your mother on one shoulder & your father on the other shoulder for 100 years, and were to look after them by anointing, massaging, bathing, & rubbing their limbs, and they were to defecate & urinate right there [on your shoulders], you would not in that way pay or repay your parents. If you were to establish your mother & father in absolute sovereignty over this great earth, abounding in the seven treasures, you would not in that way pay or repay your parents. Why is that? Mother & father do much for their children. They care for them, they nourish them, they introduce them to this world. But anyone who rouses his unbelieving mother & father, settles & establishes them in conviction; rouses his unvirtuous mother & father, settles & establishes them in virtue; rouses his stingy mother & father, settles & establishes them in generosity; rouses his foolish mother & father, settles & establishes them in discernment: To this extent one pays & repays one's mother & father."
Kataññu Suttas: Gratitude
So what ever extend one is able to motivate ones parents in direction of virtue, generosity an discerment, one works not only for the repayment of ones debts but also gives condition for possible understanding the Dhamma when hearing.
It's not sure that such giving back is possible, but it's for sure merely impossible is one does not show by deeds the attributes of virtue, generosity and discerment for oneself, not only strives for pleasure and enjoyments for oneself but also invites mother and father just in occations of such.
As the Buddha pointed out, in this way one will not only never pay back but also not reallt help ones parents.
One is clear, a virtues, generouse life of a child, his way and discerment, even if not direct explained, has impact on the parents and family, and when one starts not to simply waste away ones old merits, the possible luck like seen in the Mangala-Sutta, but also encourages ones parents not just waste them but doing merits, one does good.
Even if coming from a western or christian cultur, such as doing merits was not alien, yet in one generation it seems to have become. Less are boundage of people who are enjoying, praising and sharing deeds of merits with each other and invite neigbors and others to join.
So in this frame it might be useful to think and reflect how much benefical for oneselft and his/her beloved is actually, aside just talk and justifying, in daily life done?
Conviction, the base of all, that deeds make a different, that deeds have an effect, and that good can be reached, is the base of all and it's by doing and displaying deeds that one gives chances for others to get interested and join ways, different form the usual living on "luck" (nissaya), not knowing from where it came.
So what about the traditional way of teaching Dhamma, strating with teaching:
and really display them in daily life and social conduct as prerequisite?
(Just came to mind: My person made a small booklet, with the basic teaching, useful for everyone, as a Dhamma present especially for family and friends, far away from even ideas of my persons way. Its in German, and based on the ZzE/ATI treasures. It would be good if such would be compiled in english and other languages as well, but for now very limited in technical regards. Maybe an inspiration: Der Schlüsselband - "Über Freunde, Großzügigkeit und Tugend" - "The key-book - About friendship, Generosity and virtue", following the links the english teachings can be found)
There is a small booklet which shows well how Dhamma is taught and introduced traditional, based on the basics of right view: Under the shade of my parent's love, far, far of the "western" or modern way of useless discussions on self, and emptiness, but effective for this world, the next and even beyound. (Now my person "needs" to go for an alms round, to give other parents and childs the possibility to make merits, to work out their path, little by little as well.)
It's by the way, not out of reason, to renounce (mostly for a limited time) and ordain so to benefit the parents which are, out of that reason, encounter by the Dhamma as a "family-issue" in that way. That is why it is said that the ordination of a child is of great benefit for the parents. A very usual practice in SE-Asia. Of course it also gains it's critic if done just as meaningless ritual.
