Now I know that according to you, it accounts for billions of years, and there is no limit to accounting. But my experience is that nothing has happened and there is no "time" spent.
In reference to the number seven, Baba elaborated:
There are seven worlds [planets in evolution], seven skies, seven suns, seven moons, seven planes and seven heavens [in involution]. Why this figure seven? And sanskaras too are of seven colors. Why? Because in the very beginning, when Energy ( Pran ) clashed with Matter ( Akash ), it created seven divisions.
Each individual human being is a universe unto himself. In the head there are seven openings: two eyes, two ears, two nostrils, and one mouth. In the body there are seven parts: two arms, two legs, two openings (front and back), and one trunk.
But all this explaining of the universe and creation relates to the hair and has nothing to do with the head. So first try to get hold of the head, because out of it comes everything.
Baba drew a figure of a man's head with hair and added:
The barber's work is to shave the head. And who is the barber in this case? Mahapralaya! For when it occurs, all the hairs (universes) on God's head are shaved off.
It is said that the universes pour out of the Godhead; they are like God's hair. Your head may symbolize God and your hair the universes.
K. J. Dastur had been given notes and other written material about Baba as he was working on a biography of Baba. While Baba was giving a discourse that evening, Adi Sr. was sitting by the window of the crypt-room, listening. Dastur came and abruptly told Adi to make room for him by moving over. Not liking the tone of his voice, Adi asked why he should move. Dastur replied, "Because this is my seat."
"Have you paid for it?" Adi asked. Seeing that Adi's remark upset Dastur, Baba took Adi to task for instigating a quarrel. He then motioned to Adi to seek Dastur's pardon by touching his feet, which he did.
Adi felt humiliated, having had to bow to Dastur, but after the incident when Dastur had left, Baba explained to Adi, "You should become like dust. I scolded you to turn you into dust."
Baba continued, "You have not lost anything. What you consider to be your loss is in fact your gain. There is gain where there is loss, and without loss there can be no gain. How can one benefit and realize God without first shedding the ego?"
