Let Dus stands for ten and Ra stands for Rama. The remaining word is seh, which gets converted in to she. She is no religious word and the word closest to this and phonetically related is Shi. But Shi is related with Shiva. Shiva is very much related with Rama as Rama was blue in color according to Ramayana while Shiva’s idol is portrayed as blue in color even though Shiva is considered as pure White. Many among Hindus believe that Rama and Shiva are interchangeable. Therefore she becomes shv+i.e.+a  

Shv is an abbreviation for sub hoc verbo or sub hac voce which means under this word. i.e. implies id est implying that is, while a refers to first. Then Dussehra becomes: Dus+under this word+that is+a+Rama. It means that the ten incarnations of Vishnu are subordinate to Rama, the first historic incarnation of Vishnu. Therefore, in both Hindi and in mixed language this is the meaning. From this it can also be concluded that Shiva=shv+ia, which when e for English is added becomes shv+i.e.+a; Shiva is Rama in English. There is a lot of relationship between Sanskrit and English and other European languages.

The real meaning of Dussehra is celebration of day when Rama brought South of India under his influence, preaching Vaishnavaism and exporting Brahminism but not killing Ravana, instead marrying him with a fair Northern Indian Brahmin girl. Rama never invaded the South of India. But he did go there at the invitation of Southern Indians to end the evil in Ravana. As it appears Ravana is a respectable name and Rama should have given the name to him.  

Dussehra not only implies victory of good over evil and personal victory of Rama over Ravana, if Ramayana is considered as correct, but it also implies institutional victory of Vishnu over devils. The ten head of Ravana as described in Ramayana depicts ten evils and it required ten Vishnu to destroy them. But historically Rama is the first incarnation and the most important incarnation. By the time Hindus got the Devanagri script Krishna’s incarnation had already taken place, most probably a millennium back. 

What all this mean is that Hinduism is a religion just like Christianity and Islam are, even though in eighties India’s Supreme Court gave verdict that Hinduism is just a way of life. Rama should be worshipped just by folding one’s hand in front of his idol or maximally offering flowers at his feet. He can also be worshipped by just taking his name without his idol.
