Therefore in all ways the confidential part of spiritual knowledge is realization of the Personality of Godhead, and not His impersonal Brahman feature. One should therefore have his ultimate aim of realization not in the impersonal feature but in the personal feature of the Absolute Truth. The example of the sky within the pot and the sky outside the pot may be helpful to the student for his realization of the all-pervading quality of the cosmic consciousness of the Absolute Truth. But that does not mean that the individual part and parcel of the Lord becomes the Supreme by a false claim. It means only that the conditioned soul is a victim of the illusory energy in her last snare. To claim to be one with the cosmic consciousness of the Lord is the last trap set by the illusory energy, or daivī māyā. Even in the impersonal existence of the Lord, as it is in the material creation, one should aspire for personal realization of the Lord, and that is the meaning of paścād ahaṁ yad etac ca yo 'vaśiṣyeta so 'smy aham.
(Srimad Bhagavatam-----2:9:33-----purport).

The propaganda of the identity of cosmic consciousness with the consciousness of the individual living entities is completely misleading because even such a person or individual soul as Arjuna could not remember his past deeds, although he is always with the Lord. And what can the tiny ordinary man, falsely claiming to be one with the cosmic consciousness, know about his past, present and future?
