Deity worship is for such persons who have ample time. The thing is, Deity worship is compulsory, and you can increase if you have got time to do so. But Mangala aratrik is essential (morning arati), and Sandharatrik (evening aratri) is essential, and offering of Prasadam to Deity is essential. And nice dress, decorating the Deity with sweet-smelling flowers, colorful and very opulent dresses, jewels, incense, etc, to make Them very brilliant and attractive, that is real Deity worship.
