道 vs 途 in religious texts
sometimes it's the same but not all the time.

say, 道路 and 路途, here they mean the same thing, the way or road.

however, in the history of China, 道 has more meaning than it appears. as you know, Taoism begins with the discussion of 道. it means the essence of the universe.

another example is 道不同不相为谋, here 道 actually means the choice of life. 途 won't express the same meaning. say, 仕途 means the the life as a officer. if you feel the meaning of the word, you can feel that 道 is more likely to stress the choice made by person and 途 will emphasize the thing it is.

道 can mean morality too. this character is rich. we can discuss it all day long, but 途 won't be.
