Material life (CC and Other Books)
Sri Caitanya-caritamrta
CC Adi-lila
The compilers of the Upaniṣads speak very highly of the impersonal Brahman. The Upaniṣads, which are considered the most elevated portion of the Vedic literatures, are meant for persons who desire to get free from material association and who therefore approach a bona fide spiritual master for enlightenment. The prefix upa- indicates that one must receive knowledge about the Absolute Truth from a spiritual master. One who has faith in his spiritual master actually receives transcendental instruction, and as his attachment for material life slackens, he is able to advance on the spiritual path. Knowledge of the transcendental science of the Upaniṣads can free one from the entanglement of existence in the material world, and when thus liberated, one can be elevated to the spiritual kingdom of the Supreme Personality of Godhead by advancement in spiritual life.
