Tantra?

Tantra’ has been derived from two words: ‘Tan’ meaning ‘body’ ‘Tra’ which means ‘to defend’. Which implies that the word Tantra is meant to describe a process through which the body can be defended against all sorts of diseases and inevitable evils. In the literal sense and a more generalized form, though, it means ‘to rule’. For example, the word Rajtantra means ‘the rule of a king (raja)’ and also, the word ‘Prajatantra’ signifies ‘the rule of the people (praja)’ or democracy.According to the followers of the Tantra Vidya or the knowledge of Tantra, this is the only knowledge remnant in ‘Kaliyug’ or the present Dark Age, through which we can fight back all difficulties in our life and live merrily.
