8.13 See Comment under 8.14
8.12 - 8.13 Subduing all the senses like ear etc., which constitute the doorways for sense impressions, i.e., withdrawing them from their natural functions; holding the mind in Me, the imperishable seated within the lotus of the heart; practising steady abstraction of mind (Dharana) which is called concentration or Yoga, i.e., abiding in Me alone in a steady manner; uttering the sacred syllable Om, the brahman which connotes Me; remembering Me, who am expressed by the syllable Om; and fixing his life-breath within the head - whosoever abandons the body and departs in this way reaches the highest state. He reaches the pure self freed from Prakrti, which is akin to My form. From that state there is no return. Such is the meaning. Later on Sri Krsna will elucidate: They describe that as the highest goal of the Atman, which is not destroyed when all things are destroyed, which is unmanifest and imperishable (8.2021). Thus, the modes of contemplation on the Lord by the aspirants after prosperity and Kaivalya (Atmann-consciousness) have been taught according to the goal they lead to. Now, Sri Krsna teaches the way of meditation on the Lord by the Jnanin and the mode of attainment by him.
