Osho - Life is a dream

Osho :
You do not exist even in dream. You must sometimes have dreamed a dream within a dream. You dream that you are going to bed, you have fallen asleep and you are dreaming a dream.

There is an old Chinese story: A woodcutter was cutting wood in a jungle. He was tired, so he came down from the tree and fell asleep. He dreamed that nearby lay buried a great treasure of diamonds and gold in huge pots that were lightly covered with dirt. In his dream he thought that he would come at night and remove the treasure quietly.

If he removed it in the daytime he might be caught. Hewas a poor man and the treasure was worth millions. When he awoke, he buried a stick to mark the place and returned home. When it became dark, he went back to the spot. He found the stick in place but the pots had been removed. He went back and told his wife, ”I don’t understand whether I dreamed about the treasure or actually saw it. The stick is there all right, and there are holes where the pots were, so it is certainly not just a dream. But someone has removed the pots.”

His wife replied, ”It must be a dream. You must also have dreamed that you went out at night and saw the stick in the ground, and that there was an empty place where the pots were supposed to be. So go back to sleep and sleep in peace.” But it happened that another man also dreamed that he saw these very pots buried in the same place, and that a woodcutter had buried a stick to mark the place. When he got up from his sleep he ran to the place. He found the stick in the ground and also the vessels underneath!

He removed the pots and brought them home. He told his wife, ”I cannot understand whether I dreamed a dream or I actually saw a vision. Whatever it is, I have brought the pots home. They are proof that it is not just a dream. I must actually have seen the woodcutter burying the stick and therefore I knew where the treasure was.” His wife said, ”The pots are here. That much is clear. But if you actually saw the woodcutter marking the spot, it isn’t right that we should keep this treasure.

Take the pots to the king and let him decide.” He was an honest man, so he took the pots to the king’s court where the woodcutter had already lodged a complaint. The king was perplexed. Finally he told them, ”It is very difficult to decide whether you were asleep or awake, so I shall divide the treasure equally between you both, for the pots are very much there.” So he divided the treasure between them. That night the king told his wife, ”A very strange thing happened today: Two men dreamed the same dream.

Now it is difficult to decide whether they dreamed or whether they really saw the treasure. But the pots of treasure were actually there, so I divided them equally between them.” The queen said, ”Go to sleep, you must be dreaming.” For thousands of years this was discussed in China – did they dream it or not? Who actually dreamed? But this is what happens by the time we reach the end of life. All of life seems like a dream. It is difficult to decide whether the stick was really there and whether the pots were really buried;

whether the wife and children ever existed, or friends and foes; whether there was poverty or riches; whether there was conflict and competition; whether we really lost or won, were successful or unsuccessful. At the time of death all events pass before a man like a dream. Did we really live, or was it only a dream? Those who have known say, ”This is a dream dreamed with open eyes.” It is a dream because it has no relation to that which is. This is an intermediary state of imagination; it is merely a thought.

It makes no difference whether you saw it when asleep or when awake. The characteristic of a dream is that it is here one moment and gone the next. At the time of death all is lost. Within this dream you see another dream that is called the ego. You consider yourself the doer, the author of the dreams. You are filled with conceit, which all the world can see; only you do not see it. Everyone else is in the same state, never seeing their own, but seeing everyone else’s ego

How Induction Stove Works?


INDUCTION

Induction is a method, completely different from all other cooking technologies-- it does not involve generating heat which is then transferred to the cooking vessel, it makes the cooking vessel itself the original generator of the cooking heat.

How Induction Stove Works?


1.         The element's electronics power a coil (the red lines) that produces a high-frequency electromagnetic field.

2.         That field penetrates the metal of the ferrous (magnetic-material) cooking vessel and sets up a circulating electric current, which generates heat.

3.         The heat generated in the cooking vessel is transferred to the vessel's contents.

4.         Nothing outside the vessel is affected by the field--as soon as the vessel is removed from the element, or the element turned off, heat generation stops.

In Detail

An induction cooker uses a type of induction heating for cooking. It is chiefly distinguished from other common forms of cooking by the fact that the heat is generated directly in the cooking vessel.

A coil of copper wire is placed underneath the cooking pot. An alternating electric current is made to flow through the coil, which produces an oscillating magnetic field which creates heat in the cooking vessel over it, which must be made of a magnetic material (ferromagnetic) and electrically conductive, in two different ways.

Principally, it induces an electric current in the pot, which produces resistive heating proportional to the square of the current and to the electrical resistance of the vessel. Secondly, it also creates magnetic hysteresis losses in the pot due to its ferromagnetic nature.

Induction cookers are faster and more energy-efficient than traditional electric cooktops; moreover, they allow instant control of cooking energy, which no energy source other than gas offers. Because induction heats the cooking vessel itself, the possibility of burn injury is significantly less than with other methods: only skin contact with the cooking vessel itself (or, when high heat has been used, the stovetop for a while after the vessel has been removed) can cause harm. There are not the high temperatures of flames or red-hot electric heating elements found in traditional cooking equipment, which generates heat independent of the cooking vessel. Further, induction cookers do not themselves warm the surrounding air, resulting in further energy efficiencies.

Since heat is being generated by an induced electric current, the unit can detect whether cookware is present (or whether its contents have boiled dry) by monitoring the voltage drop caused by resistance in the circuit (which reflects how much energy is being absorbed). That allows such functions as keeping a pot at minimal boil or automatically turning an element off when cookware is removed from it.

Advantages of Induction Stoves
  • Less electricity is wasted compared with a conventional hot plate.
  • The kitchen is heated up less by waste heat. 
  • The bottom of the pan is not burned by the stove and stays clean. 
  • Food spills and boil-overs aren't burned on to the stove and are easily wiped off. Most stove-tops  are easy-to-clean glass or ceramic. 
  • The pot can be conveniently left on the stove after cooking, without residual heat from the stove burning the food. 
  • The pot reacts instantly to changes in power, like a gas stove, because the stove itself doesn't need to heat up or cool down first.

Disadvantages of Induction Stoves
  • A fan is used to cool the electronics. This can be noisy. The electronics or the magnetic field might also create a buzzing or humming noise.  
  • For safety, the stove will switch off if the pan is removed. This will interfere with cooking techniques that involve tilting or lifting the pan. Induction stoves need a minimum pan diameter to work. 
  • Pans that are too small will not be recognized and the stove will not switch on. The heated area might not cover the entire stove top. This is not an issue for boiling but can cause problems when frying. 
  • To check the heated area (typically a 5 inch diameter circle) a pan of water is heated on the stove. The pattern of the bubbles at the bottom of the pan will show the heated area.
