" But until that happens -- and however brief a life, it will take a while -- there is a terrible, hateful interlude that belongs to us alone, and during which we have no alternative but to cope with what we have done or omitted to do and to distract or placate our feelings of guilt, and sometimes the only way of achieving this is to increase that guilt, to heap up new guilt to cover the old, to overshadow or blur or minimize it, until finally all guilt has passed and there isn't a soul in the world who can remember what we did, no quick, wicked tongue to talk about it, not even a tremulous finger to point us out as having been the cause of anything.

" We are called at certain moments to comfort people who are enduring some trauma. Many of us don't know how to react in such situations, but others do. In the first place, they just show up. They provide a ministry of presence. Next, they don't compare. The sensitive person understands that each person's ordeal is unique and should not be compared to anyone else's. Next, they do the practical things--making lunch, dusting the room, washing the towels. Finally, they don't try to minimize what is going on. They don't attempt to reassure with false, saccharine sentiments. They don't say that the pain is all for the best. They don't search for silver linings. They do what wise souls do in the presence of tragedy and trauma. They practice a passive activism. They don't bustle about trying to solve something that cannot be solved. The sensitive person grants the sufferer the dignity of her own process. She lets the sufferer define the meaning of what is going on. She just sits simply through the nights of pain and darkness, being practical, human, simple, and direct. "

" We line up and make a lot of noise about big environmental problems like incinerators, waste dumps, acid rain, global warming and pollution. But we don't understand that when we add up all the tiny environmental problems each of us creates, we end up with those big environmental dilemmas. Humans are content to blame someone else, like government or corporations, for the messes we create, and yet we each continue doing the same things, day in and day out, that have created the problems. Sure, corporations create pollution. If they do, don't buy their products. If you have to buy their products (gasoline for example), keep it to a minimum. Sure, municipal waste incinerators pollute the air. Stop throwing trash away. Minimize your production of waste. Recycle. Buy food in bulk and avoid packaging waste. Simplify. Turn off your TV. Grow your own food. Make compost. Plant a garden. Be part of the solution, not part of the problem. If you don't, who will? "

" Broaching is a precise machining process in metalworking domain which uses a toothed tool called broach to cut materials into a predetermined shape. Broaching works best for odd shapes where precision machining is needed and hence finds wide application in a number of industry in India and worldwide.
Broach resembles a saw to certain extent but unlike a saw, its teeth become larger in size across its length. A broach gives shapes by roughing or removing the material, semi finishing and then by imparting the ultimate finishing. Round or odd shapes, for both internal and external surfaces, can be conveniently formed by broaching. This multi edge tool can shape any metal or metallic alloy but works best on softer materials like plastic, wood, bronze, aluminum, etc.
Resharpening of the tool
The broach that imparts shape to many work pieces can work properly only when the size and shape of its teeth are perfect. With time and usage, the teeth tend to lose its sharpness and become blunt. Using a dull broach may lead to permanent damage of its teeth. To enhance the broach life and minimize the tooling expense, it needs to be re-sharpened on time.
When to opt for resharpening
When broaching produce roughly shaped work pieces, it is definitely time for re-sharpening. However, with a little bit of watchfulness, one can even get it sharpened before it delivers poor finish or tearing. Some of the other conditions when this toothed tool will require re-sharpening are:
• Excessive hydraulic press pressure required to run the broach
• Nicks and scratches on the teeth making it dull
• Broach starts drifting
• Cutting edges show signs of wear
• Chattering occurs while broaching
Re-sharpening requires high precision. Removing excessive material from the teeth will adversely affect its longevity. Only proper sharpening will ensure time efficiency and high quality output. Teeth welding, grinding of gullets and teeth crest, reshaping teeth to proper taper are some of the methods used in re-sharpening.
Broaching, once used for machining only internal keyways, is now used for machining a plethora of shapes and surfaces for high quantity of work pieces. Broaching requires less tools than most of the other machining process and saves considerable amount of output time and hence favoured for high volume production irrespective of its high cost. In India, broaching finds wide application in the automobile industry. Therefore, a large number of players are foraying into the broach manufacturing industry on a regular basis. "
