In what way is Ishwaran an asset to Mahendra?

Ishwaran followed Mahendra wherever he went uncomplainingly. He did various chores for him like cooking, washing his clothes etc. Most importantly, Ishwaran chatted away with his master at night. Ishwaran had the skill of narrating stories on varied subjects. He more than made up for the absence of a TV in Mahendra’s quarters. He could produce and prepare delicious meals even in a desolate place.
