BG Chap 9 - Confidential instruction to go beyond the miserable world
This world is temporary and full of miseries, not habitable for any sane gentleman. This world is declared by the Supreme Personality of Godhead to be temporary and full of miseries. By saying the world is temporary (anitya), Kṛṣṇa negates the idea that the world is false. This world is temporary, but there is another world, which is eternal. This world is miserable, but the other world is eternal and blissful.
The Lord urges Arjuna, a saintly king, to worship Him after giving up the desire to enjoy this impermanent world. Kṛṣṇa asks Arjuna to engage his mind in always thinking of the Lord, to become His devotee, offer obeisances to Him and worship Him. Absorbing the mind and body in Kṛṣṇa, one would certainly reach Him. The Lord teaches here pure bhakti. One should always think of Kṛṣṇa. It is not sufficient to work hard for Kṛṣṇa while our minds wander. The king’s servant is not a real devotee of the king because, besides being dedicated to the king, he is also dedicated to his wife and other things. One’s mind should always be fixed, like an uninterrupted flow of honey, on Kṛṣṇa, who has a complexion of blue lotus. One should be absorbed in worshipping the Lord’s form and offer respects to that form with intense prema.
Unscrupulous commentators divert the mind of the reader by saying that it is not to Kṛṣṇa, but to the unborn within Kṛṣṇa that one has to surrender. Such commentators do not know that there is no difference between Kṛṣṇa's mind and Kṛṣṇa. Kṛṣṇa is not an ordinary human being; He is Absolute Truth. His body, His mind and He Himself are one and absolute. This is stated in the Kūrma Purāṇa. But because the commentators do not know this science of Kṛṣṇa, they hide Kṛṣṇa and divide His personality from His mind or from His body. Although this is sheer ignorance of the science of Kṛṣṇa, some men make profit out of misleading people.
