Approach those who have realized the purpose of life and question them with reverence and devotion; they will instruct you in this wisdom. Once you attain it, you will never again be deluded. You will see all creatures in the Self, and all in me.

If you want wisdom, seek out a teacher who is wise.  You can't get it from someone who hasn't achieved it for himself.  At best, such a teacher can only point you in the right direction.
