Teachings On Moksha in the Bhagavad Gita

Sri Krishna says in the Gita:

शक्नोतॊहैव य: सोदुम् प्राक्शरीरविमोक्षणात्।
कामक्रोधोद्भवम् वेगम् स युक्त: ससुखी नर: ||

Saknoteehaiva yassodhum praak sareera-vimokshanaat;
Kaama–krodhodbhavam vegam sa yuktah sasukhee narah.

After death, a man is what he has been just before his death. If he has not controlled lust and anger in this life, and acquired peace of mind and joy, he cannot have them after death.

That is why Sri Krishna said ihaiva इहैव (here, in this life itself) and explained the meaning of ihaiva by saying Praak Sareer प्राक् शरीरविमोक्षणात् (before the body is cast off). Such a moksha before death will alone bring about moksha after death.

My Thoughts on the same

It is while living on earth that we should attain moksha - all desires, anger, ego, hatred should be dropped and we should purify ourselves while living on earth. We need to make the place we live Vaikunta - with Bhagavan as our guide. In this Kali Yuga, mere recitation of the name of the deity helps in achieving peace and moksha.

Ways of the Bee and the Python From Srimad Bhagavata Purana

Of what avail will be the wealth and the objects of enjoyment gained by great effort for man who is naturally subject to the three types of sufferings caused by his own body and mind (adhyatmika), by external natural forces (adhibhautika), and by extra-human agencies (adhidaivika)?

I find how wealthy men, who are miserly and slaves of their senses, are ever subject to sufferings. Out of fear they get no sleep, and suspicion of others becomes second nature with them.

 Men who want to preserve their life and their wealth are both subject to fear from a variety of sources — from the ruling power, robbers, enemies, one's own relatives, birds and animals, suppliants , time, and even from oneself (through exhaustion of wealth and one's energies by enjoyment).

A wise man should therefore abandon love of sense enjoyments and the desire for wealth, both of which are productive of grief, infatuation, fear, anger, attachment, helplessness and exhaustion.

In this world, I have two teachers — the honey-bee and the python. It is from them that I learnt the lesson of renunciation and contentment.

The honey-bee taught me renunciation. Just as the honey gathered by the bee through hard labour, is taken away by others who do not hesitate even to kill it, so the hard-earned wealth of a rich man is robbed by others, killing him if need be.

Like the python I make no effort for food, but am satisfied with what chance brings. If nothing comes for many days, I lie all the time like the python without food, but with my strength undiminished.
