How to study a chess book in given configuration

I have a tablet with book loaded on it with a chessboard in front and a notebook the problem I face : mental friction: play out authors moves while understanding dense notes compare yours and look for more subvariations how do I make this process smoother like ik it's supposed to be like a maths workbook but this seems too confusing for my brain to handle, a step by step process would be appreciated

I trained with a book too. You can make the steps like this:

1. First, try to solve the position.
2. Then, take your notes.
3. Third, look for other variations. If you can't find, you can skip this.
4. Then look to the answer. It doesn't matter if it's wrong or true, take notes. Write about the tactics you didn't see. After some puzzles, if you can't see this tactics again, solve puzzles in Lichess or chess.com about this tactics.
   But the most important part is, train, but don't tire yourself. If you do, you'll get bored. This is the key.

The target.
The mechanism.
The intended result.
if i remember correctly it was @chesspriyome. shall i merge these two like how

The solution, in the old days, was to use two boards, one pocket sized. Make the moves on both boards. Once you want to start investigating variations and alternatives, play them out on the main board. When you're satisfied, you can quickly reset the position by looking at the pocket set.
Nowadays, you can make the moves on an online board e.g. by creating a study on lichess. You can then easily switch between variations and the main game. You lose the feeling of playing on a real board with pieces but gain in efficiency as there's no need to reset positions.
The trend in modern chess books is to increase the number of diagrams per game. This helps if you're using physical boards as you can refer to the diagram when setting up a position.

It's the same.
Examine it, then take notes, then solve endgame puzzles, then take notes again. And give yourself some break.

Well, you have to physically play through the moves whether you use a board or a computer. The only exception is if your visualization skiils are good enough to read a chess book 'blindfold' i.e. from the book alone without setting up positions.
