GUARANTEED PERFECTION

If you would like the vestibules of comprehension that God has bestowed you with, to develop, the key to its door is: "Use every vestibule (eyes, ears, etc.) for the purpose it was given." This is a guarantee!!! (Holy Qur'an, 14:7). Observe that there are people who even at the age of 80s and 90s or above that, have a powerful mind. How? By luck? O O, "luck" in the crux of its meaning is a non-entity. The answer is: "Struggle and right usage!!!!"
