That is the way of the spiritual and godly life, after attaining which a man is not bewildered. Being so situated, even at the hour of death, one can enter into the kingdom of God.
One can attain Krishna consciousness or divine life at once, within a second--or one may not attain such a state of life even after millions of births. It is only a matter of understanding and accepting the fact. Khatvanga Maharaja attained this state of life just a few minutes before his death, by surrendering unto Krishna. Nirvana means ending the process of materialistic life. According to Buddhist philosophy, there is only void after the completion of this material life, but Bhagavad-gita teaches differently. Actual life begins after the completion of this material life. For the gross materialist it is sufficient to know that one has to end this materialistic way of life, but for persons who are spiritually advanced, there is another life after this materialistic life. Before ending this life, if one fortunately becomes Krishna conscious, he at once attains the stage of brahma-nirvana. There is no difference between the kingdom of God and the devotional service of the Lord. Since both of them are on the absolute plane, to be engaged in the transcendental loving service of the Lord is to have attained the spiritual kingdom. In the material world there are activities of sense gratification, whereas in the spiritual world there are activities of Krishna consciousness. Attainment of Krishna consciousness even during this life is immediate attainment of Brahman, and one who is situated in Krishna consciousness has certainly already entered into the kingdom of God.
Brahman is just the opposite of matter. Therefore brahmi sthitih means "not on the platform of material activities." Devotional service of the Lord is accepted in the Bhagavad-gita as the liberated stage. Therefore, brahmi sthitih is liberation from material bondage.
