4.4 Relationship (Sambandha)

The attainment of liberation or the supreme self happens through the instruction pertaining to the knowledge of identity of the self and brahman. This instruction is the supject matter of the Upanishads. Therefore, Upanishads and liberation have a means-end relationship
 
The attainment of the supreme self happens through the knowledge of brahman, and the knowledge of brahman happens through the Upanishads. Therefore, the Upanishad is the tradition-method in the attainment of the supreme self. The instruction of brahman does not reside in any book, verse or statement, it resides only in the intellect. But, since it arises through books and so n, books are considered tradition-methods in the instruction of brahman.
 
Without the knowledge of brahman, misfortunes cannot be removed. Only through knowing that one supreme self can an individual soul cross over death. Only through the knowledge of brahman, not any other knowledge. Also, only through knowledge, not through action or worship or any other method. (Shvetaasharata Upanishad 3.8)
 
One can roll up the sky like leather, this could be possible. But, all sorrows end without the knowledge of that supreme lord, this is never possible (Shvetaashatara Upanishad 5.20)
 
Knowing that supreme lord, freedom from all bonds is achieved (Shvetaashatara Upanishad 1.8)
 
It is the loud cry of Vedanta that only knowledge leads to liberation. Knowledge of brahman happens only through the science of the Upanishads, and not anything else.
