Sages, whose blemishes are attenuated, doubts are dispelled, who have enough self-control, and who are interested in the welfare of all beings, attain Brahmic freedom.
In the previous verse, Krishna referred to inner delight, as a means to attain Brahma-nirv¡ṇa, the ecstasy of sovereign inner freedom. Here he strikes a different note denoting comprehensive vision and loving interest in the welfare of all beings.
Spirituality truly focuses on purifying and expanding the mind and intelligence, thereby generating full contentment and freedom. This implies dispelling all doubts about the Self, world, life, interactions and spiritual attainment. Discontent and doubt are the last notes of impurity and imperfection. When these too drop, the expanse is full and freedom becomes sovereign. It is a very lofty and radiant state by any standard! There is none who will not covet it!
The process implies an abiding interest in the welfare of all beings. Spiritual growth and enrichment go along with such societal interest, expanse and identification.
