"If you don't keep in touch with the original link, then it will be lost. And if you keep touch with the original link, then you are directly hearing Kṛṣṇa. Similarly, Kṛṣṇa and Kṛṣṇa's representative, spiritual master, if you keep always intact, in link with the words and instruction of the superior authorities, then you are always fresh. This is spiritual understanding.
Na jāyate na mrīyate vā kadācit nityaḥ śāśvato 'yaṁ purāṇo (BG 2.20). Purāṇaḥ means very old. Just like Kṛṣṇa, the Supreme Being, He must be very old because He is the original person. But the Brahma-saṁhitā says, advaita acyuta anādi ananta-rūpam ādyaṁ purāṇa-puruṣa nava-yauvanaṁ ca (Bs. 5.33). Purāṇa-puruṣa, the oldest person, but you will find Him nava-yauvanaṁ ca, always a fresh youth. That is God."
