Sat-Sangatvay Nis-Sangatvam

In his famous, beautiful poetical composition known as 'Bhaj-Govindam' - Aadi Shankaracharya talks about human nature - regardless of time and place, and how to achieve the ultimate universal truth.
 In one of the later verses, he says:
                   सत्संगत्वे नि:संगत्वं,  नि:संगत्वे निर्मोहत्वम् ॥    
                   निर्मोहत्वे निश्चलतत्वं, निश्चलतत्वे जीवन मुक्तिः ||

               "Sat-Sangatvay Nis-Sangatvam 
                Nis-Sangatvay Nir-Mohatvam
                Nir-Mohatvay Nischal-Tatvaam
                Nischal-Tatvay Jeevan Muktih"

Keeping the company of Saints - noble and righteous people results in being free from the company - company of vices and delusions, wrong or excessive worldly desires etc.
The state of being 'Nis-Sangatavam' - free of all company can also be translated as the Thoughtless state of mind - known as freedom from mind.

Which in turn results in being free from the 'Moha' or attachment - attachments with ill thoughts and vices - wrong beliefs, assumptions and dogmas - and thus not getting confused or perplexed and going away from the desired destination of achieving the Truth. 

This state of mind - being free from the attachments - further results in knowing and having union with the 'Unchangeable Truth'; the one and only Reality.

Knowing and establishing one's self in the Unchangeable Truth ultimately results in achieving the Jeevan-Mukti; Liberation while living in the world and from the repetitive cycle of birth and death.
As long as one is attached to a certain thing, a person or a particular personality, a particular dogma, a certain situation or environment - one is bound and cannot be called as Jeevan-Mukta.
Being free from any kind of binding is the Jeevan-Mukti - the Living-Salvation - the True Liberation.
