श्रीमद्वाल्मीकिरामायणे अयोध्याकाण्डे त्य्रुत्तरशततमस्सर्गः (18 श्लोक)
“ShriRaama, who is always on the path of Truth, stood up as soon as He saw His mother (and other queens of Dasharatha). He then in order saluted and prostrated to their lotus feet with great Bhakti”. Lakshmana and then SitaDevi also then prostrated to them while showing utmost respect and reverence.
Like SitaRamaLakshmanas, we should also show respect and affection towards our mother.
