How to get to Nirvana? I am very new to Buddhism. 
What would be the most accurate way to practise and reach to Nirvana?
Did Lord of Buddha show us?
The fourth noble truth states that the path to ending suffering is the noble eightfold path. 


Right view
Right resolve
Right speech
Right action
Right livelihood
Right effort
Right mindfulness
Right concentration


1 and 2 are the foundations of wisdom. 3, 4 and 5 are the foundations for virtue, 6, 7 and 8 are the foundations of meditation.

This is a very broad outline of the path to nirvana. You should be wary of people who give a simple precise description with promises of results like "Just follow my practice for 10 years and you'll be nearly enlightened".
