Uḍḍīyāna, always taught by the guru as natural, whoever practices it constantly, even if he is old, becomes young.

This verse emphasizes two fundamental aspects: the need for direct instruction and the importance of constant practice.Sahajaṃ guruṇā kathitam indicates that Uḍḍīyāna should be “said” or transmitted by the guru as something natural, not forced.Correct technique is fluid and organic, not violent or tense.

The term sahaja (natural, spontaneous) is significant.Although Uḍḍīyāna requires learning, once mastered it becomes as natural as breathing.Tantric texts speak of sahaja-samādhi—the state of natural absorption—and it is suggested here that properly practiced bandhas lead toward that spontaneity.

Satataṃ abhyaset — “practice constantly” — is the central message.The extraordinary benefits described do not come from occasional practice but from sustained sādhana.The aforementioned rejuvenation reflects the restoration of optimal pranic flow: when energy circulates freely, the body maintains its vitality regardless of chronological age.
