As I know wilayat is to being in an authority of someone and we belongs to wilayat of maula amirul momineen

But there are two wilayats
1. Zahiri
2. Batini

Both are wajib. I know zahiri and I also have zahiri but for batini I need amali. For that we need to do some work that is wajib on us. But i didn’t know any obligatory expect namaz roza,etc.

Can you tell me what I can do for getting wilayat a amaali

Wilaya Bateneya is specific to the Prophet and the imams, peace be upon them, by means of which they act in the universe according to the will of God, so you do not need to bother to obtain it.
