What is the suggested progressive methodology for reading Ibn al-Qayyim's books on spiritual refinement in order to gain the intended benefit?

"The advice is to read Ibn al-Qayyim's books gradually, starting with the easier ones such as 'Al-Daa' wal-Dawaa'' (The Disease and the Cure) and 'Al-Risalah al-Tabukiyah' (The Tabuk Epistle), then moving on to 'Tariq al-Hijratayn' (The Two Migrations Road) and 'Madarij al-Salikin' (The Stages of the Seekers). It is also beneficial to have a study partner and a shaykh to read to, while attempting to summarize chapters and apply their contents."
