If a loyal Zevist who performs the Dedication ritual but fails to achieve any spiritual development commits suicide, will the Gods protect her soul and escort it to Duat?
But there is one thing: the person who commits suicide is in a very very severe condition and has illnesses. And there's no solution.
They should do what they can while still alive. There are so many new articles being posted by High Priest, encourage him to read them, or you can read them to him if he is unable to read due to illness. Or you can put them in text-to-speech for him to listen to.
This person is in such a severe condition that her can barely take care of herself, and because of this her cannot continue her spiritual development.
Meditating requires only the mind. Even if he cannot vibrate mantras, he can still mentally chant them.
The Gods value those who do their best despite their conditions.
