Same reason we use Hindi words in English, it's easier to take a word for a concept from a language that has that concept, then it is to make a completely new word for said concept.

Like Yoga.

Fun fact, Yoga and Yoke, the bar tied around an oxen neck so it can plough fields, have the same indo-european-root.

It probably originates from 150 yeas of British colonisation of most of the Indian sub continent.

Also, the English language contains a number of Hindi words such as Bungalow, jhodpurs, char etc from the same period.
