Chapter 12 Bhakti Yoga Verse 7

Teshaamaham samuddhartaa mrityusamsaarasaagaraat;
Bhavaami nachiraat paartha mayyaaveshitachetasaam.

To those whose minds are set on Me, O Arjuna, verily 
I become ere long the saviour out of the ocean of the mortal Samsara!

Interpretation

Continuing from the previous shloka where He says those who worship Him by renouncing all actions in Him, regarding Him as supreme goal and meditating on Him, Lord Krishna continues to tell in this shloka what happens to such a person. He says that a person who does all the above and sets his mind only on the Lord, then the Lord comes in the ere. The meaning of ere here means before in time or earlier than. It means that the Lord will come before time, for those who worship Him and save them from the mortal samsara of the birth and death. 

Extending Interpretation to Mankind’s Life!

“Ocean of mortal samsara” is something we need to look at and understand here. Many of us relate “Samsara” to Samsaram or family life. If you look at the Sanskrit meaning of Samsara, it means “Wandering” or sometimes “aimless wandering”. Philosophers have also equated samsara to “cycle of aimless drifting” or “mundane existence”. What does all this means? Let’s try to understand why Samsara is equated to samsaram or family life. There are two cycles of life that go parallelly to an individual, cycle or mortality and cycle of immortality.
Cycle of mortality is also called as mundane living, as we follow the mortal as the aim of life. Within us, body is mortal and soul is immortal. So, if you follow the mortal or body, it will pull you to everything that is linked to the pleasure of the body or senses.

That includes power, money, comforts, marriage, sex, children, affections, love, attachments etc etc and the list is endless. All this will give you immense pleasure and you will feel scared to lose them. So, you indulge in all sorts of things to protect them and to hold on to them. Like if some swami tells a rich businessman that he would face losses in business, that business man will do everything mortal like visiting temples, offering gifts to God, constructing temples etc to save his business from getting into losses. He will not do anything immortal or something touching his soul to introspect.
This is nothing but “Samsara” or mortal living. Each one of us are so bothered that our actions are directed at protecting their happiness and things related to senses. What about soul here? Are we bringing soul anywhere into the picture? If the purpose of the body is to educate the soul and if a person is engaged in satisfying the needs of the body, then what happens to the soul? The soul will be a silent witness to the waste of time that the body is doing  and keeps taking different bodies till the time a person realises the importance of soul needs over the bodily needs.

Coming to the soul needs, it doesnt need anything except knowledge. Knowledge is the path for salvation and soul’s journey is only towards acquiring that knowledge. If this thought strikes a person, he will abandon the needs of the body and goes on the path of enlightenment of the soul. He will come out of the cycles of happiness and sadness that body gives. He will not be affected by the death of anyone or a loss of job or money nor will celebrate the success or gain of wealth or marriage or birth of children. For soul to get salvation, coming out of this Samsara is required and that is what Lord Krishna says He will bestow to a person who fixes his mind only on Him and meditates on Him.
