They are certainly not idols or statues but the living Presence of Lord Rama and Sita Mata. Their dual Presence brings the courage and strength to face and overcome every obstacle and difficulty as well as embody the highest human qualities such as nobility, courage, generosity, and all that makes our human life high and worthwhile preparing us for the still higher spiritual life. Generally the vigraha of Hanuman ji should accompany them because it gives not only the strength to go through the difficulties but also to overcome them swiftly.
