May I suggest to the seeker of truth do the following NINE STEPS for purification of the mind:
Clean their mind, their heart and their soul real good.
Clear away all the prejudices and biases.
Read a good translation of the meaning of the Holy Quran in a language that they can understand best.
Take some time.
Read and reflect.
Think and pray.
And keep on asking the One who created you in the first place, to guide you to the truth.
Keep this up for a few months. And be regular in it.
Above all, do not let others who are poisoned in their thinking influence you while your are in this state of "rebirth of the soul."
The rest is between you and the Almighty Lord of the Universe. If you truly love Him, then He already knows it and He will deal with each of us according to our hearts.
Peace to you and Guidance from Allah the One Almighty God, Creator and Sustainer of all that exists.
