Hesed, the right hand, should be above all our thoughts and feelings because bestowal, love, and compassion are above everything. On the whole, Hesed (mercy) is regarded as a weakness in our world. If someone loves me so much that he always feels merciful towards me, I begin to take advantage of it egoistically, and very soon begin to “sit on his head.”
But in the spiritual world, it is the opposite. Mercy (Hesed) is the greatest, most sublime attribute. The whole spiritual world is founded on it.
A person who attains this attribute brings all his desires and intentions (“head” is the intention) to the level of above reason. He works in faith above reason and aims his intentions only for bestowal.
Thus, the Torah tells us that the Creator puts His hand on the head of the burnt offering as if He gives it an intention. This means that all the thoughts and desires, the mind and the heart, are dominated by a new force that has been given by Him, the force of mercy.
