The Brahma Sutras together with Sage Sankara's commentary thereon do not contain the higher wisdom. They are intended for those who are incapable of thinking rationally.

Sage Sankara's commentary on the Brahma Sutras is not on a philosophical basis, but on an orthodox and mystic basis, with an appeal to the Vedas as a final authority.

In Brahma Sutra Sage Sankara takes the position that there is another entity outside us, i.e. the wall really exists separately from the mind. This was because Sage Sankara explains in Manduka that those who study the Sutras are orthodox minds, intellectual children, hence his popular viewpoint to assist them. These people are afraid to go deeper because it means being heroic enough to refuse to accept Sruti, and God's authority, in case they mean punishment by God. 

A Gnani says the scriptures for children, but wise seekers will think rationally.

In Brahma Sutras Sage Sankara takes for granted, assumes that a world was created: He there mixes dogmatic theology with philosophy.

That God created the world is an absolute lie, nevertheless one will find Sage Sankara (in his commentary on Vedanta Sutras) clearly says this! He has to adapt his teachings to his audience, reserving the highest for philosophical minds.

The text of Brahma Sutras is based on religion, dogmatism, but in the commentary Sage Sankara cleverly introduced some philosophy. If it is objected that a number of Upanishads are equally dogmatic because they also begin by assuming Brahman, only a few Upanishads do not but prove Brahman at the end of a train of proof.

Scholars' translation of Brahma Sutras in Sacred Books of East must be read cautiously as he has not understood its highest sense, e.g. for Advaita, they wrongly put "Unity" instead of “Non-duality."

Sage Sankara gave religion and scholasticism and yoga no less than Advaitic wisdom, to the seeking world. He was great enough to be able to do so. His commentary on Manduka is pure philosophy, but many of his other books are presented from a religious standpoint to help those who cannot rise up to philosophy.:~ Santthosh Kumaar
