It warns that inner timidity and crippling self-consciousness weaken one’s fitness for dharmic duties; spiritual life requires steadiness (dhairya) and clarity of mind to act rightly.
While not directly teaching bhakti, it implies that sustained devotion needs courage and consistency—excessive fear of judgment can obstruct regular worship, vows, and service.
It reflects a Vedanga-style concern for eligibility and effective performance of duties: mental disposition is treated as a key factor for competence in ritual and disciplined practice.
