The notion that inspiration is something that happened thousands of years ago, and was then finished and done with. . . the theory that God retired from business at that period and has not been heard from since, is as silly as it is blasphemous.
Each human being was given two qualities: power and the gift. Power directs us towards our destiny; the gift obliges us to share with others what is best in us.
Alexander, Charlemagne and myself all tried to found an empire on force and we failed. Jesus Christ is building an empire on love, and today there are millions of people who would gladly die for His sake.
Poets should be law-givers; that is, the boldest lyric inspiration should not chide and insult, but should announce and lead the civil code, and the day's work.
Even if the being is not entirely purified, varieties of inspirations and powers may come down from above but this may lead to serious errors. Inspirations from above mixing with the impurities from below get all muddled up and the sadhak takes this for an absolute command. Many a sadhak has thus fallen into danger. Therefore, one must particularly lay stress on the purification of the being.
Beware of addictive medicines. Everything in moderation. This applies particularly to the Internet and your sofa. The physical world is ultimately the source of all inspiration. Which is to say, if all else fails: take a bike ride.
