Before looking into the answer let us first look at few questions.
- Why did Government create prison houses?
- Government has the power to release all the prisoners.Why doesn't the head of Government release all of them?
Many Vaishnav acharyas compare this material world(that includes different heavenly and hellish planets) to a prison house.
So why was this material world created?
Actually This material world is eternal it was never created.(BG 13.20)
Material nature and the living entities should be understood to be
beginningless. Their transformations and the modes of matter are
products of material nature.
For those who are envious of GOD are sent to this world. We can see that everybody here wants to lord it over material nature; some one wants to be a master of his family, someone master of his country, master of his job etc. But in reality Krishna is the master of entire cosmic creation. I discuss this matter in more detail in my answer here .
Why Doesn't Krishna grant liberation to all?
The living entities in this world may be broadly classified in 2 categories.
- those who are engaged in sense gratification(serving the illusory
energy of krishna )
- Those who are engaged in service of God(PATH OF SELF REALIZATION)
And Krishna says:
As all surrender unto Me, I reward them accordingly. Everyone follows
My path in all respects, O son of Pṛthā.
So if someone wants to serve external illusory energy of GOD; Krishna grants his desire and sends such person to this world/or keeps the person in this world.
Basically God doesn't interfere with out free will(I discuss this free will in my above linked answer).Because there is no point in showing a gun to a girl and asking her to say 'I Love You' :D . In that circumstance anyone will say as you dictate. God does not impose himself on us. We came here by our wish so he wants us to return on our own wish.
So point here is :He sent us to this world because we wanted to come here.
How do we know that Krishna respects our will?
At the end of Geeta Krishna Says :
Thus I have explained to you knowledge still more conﬁdential.
Deliberate on this fully, and then do what you wish to do.
So here he is not forcing Arjuna to carry out His(Krishna's) will instead asks Arjuna to do as he wishes to.
In addition I would also mention a small story(I guess its a folk tale but i'm not sure):
Story goes roughly like this:
Once sage Narada was visiting different places of pilgrimage on earth where he saw many people engaged in worshiping Vishnu. He was bewildered as to how come Vaikuntha is so vacant. These people are so pious they must be in Vaikuntha.
So when he reached Vaikuntha He asked Lord Narayana about it. lord said 'You can bring all of them here if they wish to'. Narada became happy and came back on earth.
He asked people if they desire to come to Vaikuntha. Half of them did not know what Vaikuntha was and others were just not interested since they were deeply attached to their kinsmen etc. then Narada realized what is the condition of living entities of this world.
P.S.: I have given a crude example of Prison houses built by government. SO Based on criminal actions of person judiciary system send a person to prison. however Krishna sees intentions and desires and accordingly places a person in different abode.Krishna being the supersoul in everyone's heart is aware of the intentions of all living beings.
Yet in this body there is another, a transcendental enjoyer, who is
the Lord, the supreme proprietor, who exists as the overseer and
permitter, and who is known as the Supersoul.
Great Acaryas have descended in this world over period of time.
Someone might ask are Acharyas(great Vedantist such as Shankara,Ramanuja,Madhav etc.) envious of GOD?
In answer we can look back to our example of Prison House. Sometimes police in-charge, minister or in some cases even head of state may enter a prison to see that administration is going on well. However it is not wise to think that they are prisoners.
Basically there are two types of living entities
- Nitya-Mukta(Eternally liberated)
- Nitya-baddha(Eternally Bound)
So Most of great Acaryas(Not all may be) are considered as Nitya-Mukta or are considered as incarnation of God.
They descent by their own will for delivering the fallen souls.Ex. if above mentioned great acaryas had never descended to this world we would have never been able to discuss this matter as we are doing right now.
I wish to be liberated. Why am I still in this world and Not liberated?
Again revisiting our example.If prisoner says 'release me'; will authorities release him? obviously answer is 'No'.
To release a prisoner there are 2 main factors.
- What is the punishment give?has he served the period?
- Has he transformed;and is all criminal mentality Gone?
So here in our case above point 1 will correspond to:
How much baggage of Karama do you carry? You have to repeat cycle of birth and death untill you have suffered or enjoyed for your past karma.
2nd Point will correspond to
Do we really have sincere desire for liberation and are we really trying hard for that?
Krishna Says(BG 9.34):
Engage your mind always in thinking of Me, become My devotee, offer
obeisances to Me and worship Me. Being completely absorbed in Me,
surely you will come to Me.
Krishna repeats above verse in 18.65
And finally He says :
Abandon all varieties of religion and just surrender unto Me. I shall
deliver you from all sinful reactions. Do not fear.
So we have to examine ourself across these factors. We just cant say 'oh!I want moksh' and that Krishna will come and liberate you.
That is like saying 'Oh Krishna!Please make me rich' and expecting that he will come and make you rich then and there.
This is common sense. After you cultivate a plant you have to wait for long time till that plant becomes tree and gives you fruits.This is simple law of nature. And being in this world we are bound by these laws of nature.
I also disagree* with the statement that according to you Ramkrishna makes:
The reason being;if Krishna gave liberation to anyone randomly(withou any qualification); then that would mean that Krishna is biased.
But it is confirmed in Geeta and Vedanta sutra that Krishna is not biased towards anyone.For Him everyone is equal.
note: * I disagree if he meant that without any qualification moksha is given. Sometimes it may seem like a person is all of the sudden liberated, but we do not know of his pious credit and spiritual advancement.
