Thought is in time and by giving it up, one moves into Silence which is of the plane of Timelessness. One can effectively give up thought only by surrendering it to the Divine or raising the mental plane to that of the inner Divine. Thought related to any other end is not likely to fall away. Thought loses its force over the mind when the person deep below begins to recognise that thought is no endowment and knowledge is possible only when it ceases. Unless and until the thought offered is strongly felt to be an inhibition, a curse, the Divine does not accept the offering.
Mind still dwells on various thoughts about offering thoughts.
This principle is true for all offerings. What we still value cannot be offered effectively, because it means one is enriching the Divine by his offering to it something valuable. Donation is a word contrary to the spirit of offering and really inimical. It is a self-defeating movement to turn an offering into a donation. As all real offering will have an unsublimated vibration of donation, donation may have an unconscious element of offering in it.
