युञ्जन्नेवं सदात्मानं योगी विगतकल्मषः ।
सुखेन ब्रह्मसंस्पर्शमत्यन्तं सुखमश्नुते ।। ६.२८ ।।

yuñjann-evaṁ sadātmānaṁ yogī vigata-kalmaṣaḥ |
sukhena brahma-saṁsparśam-atyantaṁ sukham-aśnute || 6.28 ||

Krishna speaks about the further development the seeker has to aim at and achieve:

Pursuing the inner contentment and restfulness steadily and steadfastly, the yogi becomes blemish-free. He comfortably enjoys the supreme delight arising from the communion with Brahman.

Spiritual pursuit, says Krishna, has to be regular, sustained and wholesome. When the sadhaka becomes sufficiently pure and sublime, he begins to experience the unhindered comfort and contentment, arising from Brahman.

Krishna calls this wholesome comfort as Brahma-samsparsa-sukha. If the earlier sukha was inner and Self-born, this is wholesome and unlimited. As Brahman is all-pervading and full, the delight born of Brahman also becomes equally so. The dimension and magnitude change appreciably. Krishna says atyantam sukham asnute – he literally eats or ingests the unending delight – not in trickles, but in much larger measure, as a sumptuous meal.

The small measure of inward comfort the seeker enjoys during his meditation gives place to the ceaseless delight and poise even when he interacts with the world around. This state of expansion is quite pronounced and must be achieved. Krishna emphasizes this point over and over again.

As in the case of the sthita-prajna discussion in chapter 2, where he began with atma-sthiti (2.55) and took it to the comprehensive Brahmasthiti (2.72), here too Krishna takes the sadhakas from limited, time bound meditational absorption and Self-state to the unlimited expansion of Brahma-samsparsa-sukham. The idea conveyed is one of unmistakable expansion. This is possible and must be achieved by the earnest seeker.

To clarify the state further, Krishna describes how the self-realized Knower perceives the world and its objects, and how his vision is always steeped in oneness and homogeneity, despite the countless, variety perceived by the senses.
