Every debit has its corresponding credit and this equality between debits and credits is the essence of the double entry principle. When a journal entry is passed, every debit has a corresponding credit and this is verified by totaling every page of the journal. However, when the journal entries are posted to various accounts in the ledger, the debits and credits get scattered and recorded in different accounts. Thus the individual debits and credits forego their identity and get merged. At this stage it is necessary to ensure that posting into ledger has been correctly done and to check whether the equality between debits and credits has been maintained throughout. For this purpose, a statement showing the balances of various accounts is prepared. This statement is known as ‘Trial Balance'.
