There are also those that do not know these methods, but simply by hearing about Him from others, they engage in His worship. Because they have faith in what they have heard, they too transcend death.
Bhagavad Gita - Chapter 13 - Prakrti Purusha Viveka Yoga - The Yoga of Differentiation Between Matter and Consciousness
You should understand that whatever exists, whether moving or non-moving, is simply manifest from the combination of the field and the knower of the field, O best of the Bharata Dynasty.
One actually sees when he perceives the Supreme Controller as being situated in all living beings, and realizes that neither the Super Consciousness nor the individual unit of consciousness is perishable.
By seeing the Supreme Person situated in all places equally, one does not become degraded. Thus he attains the Supreme Abode.
One who realizes that all activities are performed by material nature, understands that he is not the doer.
When one truly sees, he ceases to identify the body as the self. Realizing that all living beings are equal, he attains the Brahman conception and sees them expanded everywhere.
O Son of Kunti, the Super Consciousness has no beginning, He is transcendental to the modes of nature and He is unlimited. Although He is situated within each individual body, He neither acts nor is He affected by any action.
Just as the subtle element of all-pervading space does not mix with anything, similarly, the individual unit of consciousness does not mix with the material body, although it is situated within.
O Bharata, just as one sun illuminates the entire universe, the occupier of the field illuminates the whole field.
One who knows and sees the difference between the body and the self and who understands the process of liberation from material bondage, also attains the supreme goal.
