This paper explores the theme of Sufistic achievements' culmination from a methodological perspective. The type of research used is descriptive qualitative with the literature study method. The results are presented descriptively by collecting data, studying, and analyzing it according to literature analysis. The results of this research indicate that in building Islamic thought, there is a study called ittihad, al-hulul, which is spiritual construction in-depth to merge with Allah SWT through self-purification by taking mujahadah and riyadah continuously with the stages of takhalliy, tahalliy, and tajalliy. The highest peaks of Sufism vary but are formulated in three forms: Musyafah, Tajallay, and Musyahadah. Suppose it is relevant to diversity in Indonesia. In that case, Sufism is still considered urgent so that humans are not dazzled by the glitter of the world and always draw closer to God and cultivate spiritual values so that Sufism throbs in every aspect of life.
