Every individual has a high skyscraper of his entire being, an accumulation of sanskaras of millions of previous lives. Meher Baba leaves the skyscraper standing as it is. He goes in like a termite into the foundation and carves it out, making the entire foundation hollow. Then He recedes. When the proper time comes, He passes over the whole structure and it topples down in a fraction of a second. No other agency is required to do it. He does it. He sows the seed and the latter result automatically follows.
