Take a Guide! – Why? What? Who?
Why take a Guide?
Our Prophet is of the highest station in the Divine Presence, a representative of Allah among His people; and he was taking a guide. This shows that everyone asking to reach the Divine Prescence needs a guide. Our Prophet was always following the orders of Jibril, doing every action and speaking according to Allah's orders as brought by Jibril. (Angel Gabriel)
For purification we need guidance. We have (an inner guide) but with it is the ego, which is fighting up to the end. We need to learn methods from a master to fight the ego. No one becomes a doctor just by reading books. .... character is communicable. Whoever sits with Prophets (or saints) will absorb good character.
We need Divine Love to be put in our hearts - otherwise we can’t stop fighting the endless desires of our egos, enmity, envy and jealousy. When Divine Love enters our hearts everything else is going to be cheap and of no value.
The love of God is not easy to attain for we cannot imagine Him; therefore Allah Almighty made the Prophets apostles of His love.
