Basically what is positive thinking-we live n this world with lot of advantages and disadvantages at each moment. Normally it is human to think momentarily to derive benefit to self. f a second thought is given we can realise the effect of our action, how it is going to benefit/harm others. If we decide to take one step which woud help others but harm none this can be considered positive thought, all other approaches as negative. This can only be a guide line. Day in and day out we keep facing such situations endlessly. when once we are attuned to take positive decisions we always proceed rightly.
