Srimad Bhagavad-Gita :
Chapter-5. ( Karma-sanyasa-yogam )
Slokam-21. ( Such a liberated person is not attracted to material sense pleasure or external objects but is always in trance, enjoying the pleasure within. In this way the self-realized person enjoys unlimited happiness, for he concentrates on the Supreme. )
Bahyasparseshvasaktatma vindatyatmani yat sukham,
sa brahmayogayuktatma sukhamakshayamasnute.
bahya-sparseshu = in external sense pleasures;
asaktatma = one who is not so attached;
atmani yat sukham vindaty = find happiness in his atma ( Self ) itself;
brahma-yoga-yuktatma sah = concentrated in brahmam, and connected to Self;
akshayam sukham asnute = enjoys unlimited happiness.
In this slokam Lord Krishna again clarifies yoga or the science of the individual consciousness attaining communion with the ultimate consciousness and how this relates to equanimity of actions. Without any other desires internal or external only the person who relishes and revels in the atma or eternal soul is alone eligible for realisation of the Brahman or the spiritual substratum pervading all existence and the bliss accompanying it. The communion of the atma is the same as the communion of the Brahman for they both possess the same eternal nature and the only way this communion can be attained is through mediation of yoga and no other way.
If a person is inclined to attachment to sensual pleasures they will never have the opportunity to experience the transcendental bliss of the realisation of the Brahman or the spiritual substratum pervading all existence. But a question may be raised what happiness can a person derive from life if they have introverted their senses and are averted to sense objects.
Lord Krishna states the compound words sukham-aksayam meaning unlimited happiness is what such persons attains for with disconnection to the senses and objects of the senses a natural detachment arises which frees one from worldly desires allowing one to focus within on the eternal atma or eternal soul where one tastes boundless joy and experiences unlimited bliss.
In the moksadharma section of the Mahabharata it states that: The pleasures of the senses in this world and the joys of heavenly pleasures cannot be compared to even 1/16th part of the pleasure one derives from renouncing the desire for material sense gratification.
This is the essential component that paves the way for perceiving the Brahman or spiritual substratum pervading all existence, atma tattva or realisation of the soul and moksa or liberation from the material existence and cognition of the ultimate truth of the Supreme Being.
The reason why a person is free from delusion and has there mind fixed in transcendence is now being given by Lord Krishna. The word sparsesu means sense pleasures and those attached to them are called spharsa. But one whose mind is unattached and is withdrawn internally ceases to crave, yearn and desire for indulging in the objects of the senses.
Such a person attains the sublime and serene bliss that is the nature of the atma or soul. Having attained the wonder of atma tattva or realisation of the soul one continuously identifies with the Brahman by being immersed in this consciousness and experiences never ending bliss.
Here Lord Krishna describes the reality for the person who desists from attachments to anything except the atma or eternal soul and who derives all pleasures exclusively from their internal relationship with the atma relinquishing all desires for sensuous material enticements and instead delighting in brahma-yoga or the science of the individual consciousness attaining communion with the Ultimate Consciousness by realising the spiritual substratum pervading all existence.
Such a person attains sukham- aksayam or imperishable happiness. Next it will be illustrated how desire for material sense gratification can be easily abandoned.
So it can be understood that if even by remembrance of the potencies of the Supreme Lord so much happiness can be gained then what can be said for one who devotes themselves wholeheartedly to the Supreme Lord in a concentrated manner.
