In the first six chapters of Gita,¬†the living entity has been described as a non material spirit, capable of enriching himself to self realization by different types of yoga.¬† In the next 3 chapters, Krishna explains how by practicing Yoga in full consciousness of Krishna, with the mind attached on Krishna, one can recognize the ultimate knowledge of Krishna.
The Lord is omnipresent in all material and spiritual energies. The taste of water, the light of the sun & the moon, the sound -'Om', the ability or intelligence in man, the fragrances of the earth, the heat of the fire, the strength of the strong, all represent Krishna. Krishna is also the sex life which is not contrary to religious principles. Krishna is the original seed for everything, yet He is independent.¬† Only by surrendering unto Krishna, one can overcome the modes of material nature.
The Lord further advices Arjuna to render devotional service to the Lord in full knowledge of what he is doing and this would free him from material desires and worldly attachments.
All living being are born into delusion, bewildered by dualities arising from desires and hatred. Only the pious souls can take to devotional service. In the Krishna Consciousness one can understand how the Supreme Lord is the governing principle of material manifestation.
The Lord further emphasises on remembering the Almighty through one's life, and at the time of death. It is only this that will help a person attain his supreme abode,¬†beyond this material world.
To practice yoga one has to first close the doors of all¬†sense-enjoyment and not indulge in self gratification. This is the only way to focus ones mind on the Supreme Lord.
As Arjuna is non-envious, Krishna reveals to him, the ultimate knowledge which can bring total relief from material existence.
Those with total faith in the Lord shall be relieved from material existence while those devoid of faith, shall remain in the cycle of birth and death.
Lord Krishna advises Arjuna to do whatever he is doing, with love and devotion for Krishna. It is so simple and the result will be the highest liberation- attainment of Krishna.
Krishna is equal to all but is naturally partial to His devotees. Even if a devotee falls, Krishna saves him and re-instates him. Devotion is open to one and all, and by it, all can attain Krishna. Therefore Krishna's final instruction is, "Engage your mind always in thinking of Me, become My devotee, offer obeisance to me and worship Me. Being completely absorbed in Me, surely you will come to Me."
