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. This is the only spiritual value of it. Offering' means to deposit with the Divine 'nuclear waste' which the Divine alone can receive and neutralise. It does not maen the devotee giving something valuable to the Divine for its use.
