Around the twelfth century, Sufi Silsilas started forming in various regions of the Islamic world. These silsilas were meant to represent three significant aspects of Sufi practice and belief.

Firstly, they symbolized the continuous link between the master and the disciple. This suggests that the teachings and spiritual guidance of a Sufi master were passed down through generations, ensuring that the knowledge and wisdom were maintained and shared.

Secondly, the formation of these silsilas emphasized the unbroken spiritual genealogy to the Prophet Muhammad. This means that Sufi practitioners believed their spiritual lineage could be traced back to Prophet Muhammad, connecting them to the foundations of Islam.

Lastly, the silsilas represented the transmission of spiritual power and blessings to devotees. Sufi masters were seen as conduits of divine blessings and spiritual power, and their disciples would receive these blessings through their connection to the master.

The correct answer is option 4, which includes all three aspects mentioned above.
