Aksara Parabrahman Yoga-Bhagavad Gita Chapter 8 [Attainment of Salvation]
Krishna Said > Shaloka: 12
English
The yogic situation is that of detachment from all sensual engagements. Closing all the doors of the senses and fixing the mind on the heart and the life air at the top of the head, one establishes himself in yoga.
After being situated in this yoga practice and vibrating the sacred syllable om, the supreme combination of letters, if one thinks of the Supreme Personality of Godhead and quits his body, he will certainly reach the spiritual planets.
Purport
To practice yoga, as suggested here, one first has to close the door of all sense enjoyment. This practice is called pratyahara, or withdrawing the senses from the sense objects. Sense organs for acquiring knowledge, such as the eyes, ears, nose, tongue and touch, should be fully controlled and should not be allowed to engage in self-gratification. In this way the mind focuses on the Supersoul in the heart and the life force is raised to the top of the head. In the Sixth Chapter this process is described in detail. But as mentioned before, this practice is not practical in this age. The best process is Krishna consciousness. If one is always able to fix his mind on Krishna in devotional service, it is very easy for him to remain in an undisturbed transcendental trance, or in samadhi.
It is clearly stated here that om, Brahman, and Lord Krishna are not different. The impersonal sound of Krishna is om, but the sound Hare Krishna contains om. It is clearly recommended in this age that if one quits his body at the end of this life chanting the maha-mantra, Hare Krishna, he will reach the spiritual planets. Similarly, those who are devotees of Krishna enter the Krishna planet or Goloka Vrndavana, whereas the impersonalists remain in the brahmajyoti. The personalists also enter many innumerable planets in the spiritual sky known as Vaikunthas.
