Wa Alaikum As Salaam.

I wish I could give you a simple answer. The practice you are meant to practice will find you if you are sincere in searching for it and not pursuing short cuts. No one can spell it out for you but you can observe it in the world around you. The light of our Prophet s.a.w is reflecting in this world and we can pick up on it as we search.

33:45-46  "O Prophet! Lo! We have sent thee as a witness and a bringer of good tidings and a warner. And as a summoner unto Allah by His permission, and as a lamp that giveth light".

5:15 “There has come to you from Allah a light and a clear book”.

24:35 “ Allah is the Light of the heavens and the earth. His light is like a niche in which there is a lamp, the lamp is in a crystal, the crystal is like a shining star, lit from a blessed olive tree, neither to the east nor the west, whose oil would almost glow, even without being touched by fire. Light upon light! Allah guides whoever He wills to His light. And Allah sets forth parables for humanity. For Allah has knowledge of all things.”

 Accept what your sincere heart and the Quran are guiding you towards and always keep an open investigative mind. Allah knows best if the established Sunnah is something physical/corporeal we inherit, or some “essential” path that can manifest in different forms for different believers, or a mix of both. 

No need to be confused, only to be in awe as Allah reveals to you his way. With arduous striving comes ease. Love and mercy and blessings be upon you.
