For most of us talambralu is probably the most fun event in the marriage . The bride and the groom shower one another with pearls & talambrAlu (rice mixed with saffron & turmeric). Another reason is the photos taken during talambralu are probably the best :-). I have been trying to look for the significance of them but so far have only found some superficial explanations , here is one of them.
This denotes the couple’s desire for happiness, enjoyment and contentment. Initially they take turns to shower the rice as it progresses it gets more entertaining when they begin to compete with each other.
