We living people can give back to the deceased when we do all good deeds, whether we recite Buddha or set them free, but the deceased can only get one-seventh of the merits, so only when we do good deeds and repay your mother can she be happy.
Even if you put socks on your mother in some ways, if your mother is still suffering from three evils, won't she suffer other hardships! Therefore, the most fundamental way is to let her old man walk on the good path, or even go to the paradise, such as the western paradise and the oriental glass world. You will know everything after reading the Tibetan scriptures.
You can ask me again if you have any questions. I hope the dutiful son finally gets what he wants!
There is no amitabha in the south!
