This verse from the Bhagavad Gita emphasizes the importance of faith, discipline, and knowledge in attaining inner peace and spiritual fulfilment. The term "shraddhāvān" refers to those who have unwavering faith and trust in the divine teachings. They approach life with sincerity and earnestness, seeking to understand the deeper truths of existence.

The verse suggests that those who possess faith and dedication (tatparaḥ) along with control over their senses (sanyatendriyaḥ) are able to attain true knowledge (jñānaṁ). This knowledge is not merely intellectual, but it encompasses a deep understanding of the self, the universe, and the divine. It is acquired through introspection, contemplation, and adherence to righteous principles.

Furthermore, the verse emphasizes the transformative power of knowledge. Once one attains true wisdom (jñānaṁ labdhvā), they move beyond the cycle of worldly desires and attachments. This wisdom brings about a state of supreme peace (parāṁ śāntim), which is characterized by tranquillity, contentment, and liberation from suffering.

The phrase "achireṇādhigacchati" indicates that this attainment of peace is not a distant goal but can be realized swiftly. It suggests that by cultivating faith, discipline, and knowledge, one can experience profound inner transformation and liberation from the burdens of material existence. In essence, this verse teaches that the path to inner peace and spiritual enlightenment begins with faith and discipline, leading to the acquisition of true knowledge and ultimately culminating in supreme peace. It highlights the transformative journey of the individual soul towards self-realization and liberation from the cycle of birth and death.
