Tariki, it is a matter of focus. Monotheistic religions focus on their one God. Indian religions (hinduism, Sikhism, Buddhism, Jainism) focus or responsibilities and righteous action. Either the Gods are absent or they are less important than 'dharma'.
I would see it as focusing on the word of their one God. Which in consequence leads to the confusion between word as text and the Living Word. Following on, true "dharma" can only come by grace via the Living Word.
