What is Dharma

Since several days this question, has been coming forward and needed to be answered as to 'What is Dhrama' but before this question is taken up, another concept should also be answered at this point.
Life is a journey, which goes thru several paths, some are well lite while others are dark, some are smooth while some are rough. During this journey one comes to several crossings, where one has to decide which road or path to be taken. Whenever such a crossing comes one is left with one's own experience and that of the other's when they had came to a similar crossing, but as it can only be similar and not the same, so what to do, it is here that Dharma comes to rescue. So Dharma is which tells one the right path. So we can easily say that Dharma is which tells us the right path. Now comes what is Right and what is Wrong. What is right could be wrong for another and what is wrong for one could be right for another. Does Dharma also change, then the answer is yes Dharma also changes, so what is dharma is also adharma, then yes, what is adharma can also be dharma.

This can easily be explained in a simple example
Is eating meat Right or Wrong?
For a Cow it is wrong but for a lion it is Right.
If we look at the jaws and digestive system of both the animals we can clearly say what is right and what is wrong. But the Human's have a system where the jaw and digestive system is for both, so it is here that we stand at a cross road and would like to know what is Dharm yukt it only here that the answer becomes self explanatory, and answers our query and helps us to define Dharma. So it is our Dharma to be vegetarian if one has a choice between vegetarian and meat foods. Take the case of Hindus which had its base in the Gangetic planes where the choice of both was there, it was said that one should be vegetarian, as being vegetarian was best for the human body, but take the case of Chritians and Muslims which had its starting in the Deserts where there is hardly any vegetation, meat is the only food and vegetarian food a luxury, these two religions opted for both the foods. So for the followers of Vedas it was vegetrian food Dharm yukt, while for the muslims and christians it was both. Also look at another example Christians migrated to colder places so even got wine as parsad. Take the case of Tibetian monks meat is not a taboo as Tibet is also a place where vegetation is not much.
