Hey, you two (Varun Kochhar and mohan.sic), kindly take your fight elsewhere.
I agree with pannet that perhaps there is confluence of eastern and western mindset which is true for many of us and it permeates all aspects of our life ...
Teaching for "Sense of satisfaction" is too abstract. A teacher also needs material wealth for his sustenance. In Vedic gurukul system, students did not pay in terms of money but did pay with grains, physical labour, milch cattles etc etc .... In modern days, all of this is replaced with money.
From my POV, asking for contract note of stock market trainers is primarily to weed out bogus teachers
At the same time, I also accept that stock market is infinite and expecting that teacher himself knows everything worth knowing is stupid.
