In order to remove the illusions of understanding, deep inquiry is a very strong tool. The student first needs to detach himself from the restless of his mind and find out the roots from where all his inner noise is coming. There are five sub-conscious and un-conscious hidden layers of these roots. Normally, everybody is living unawares of their presence. Once the attention is turned inwards through right questioning, they start to untangle. One not only becomes aware of these roots, one also understands their shattering effects upon one's peace and happiness. All sane minds then start withdrawing from their attachments with these discomforting causes of agitation.
