Acharya Prashant explains that devotional singing, or 'Bhajan', is a method designed to purify the mind. Since the human mind is naturally captivated by music and songs, sages integrated spiritual messages into melodies. He notes that while ordinary songs often contain harmful content disguised as sweetness, saints provide the 'medicine' of truth through the 'sweetness' of music. This method makes it easier for the mind to remember and internalize spiritual teachings, replacing worldly distractions with divine contemplation. He further clarifies that 'Bhajan' acts as a constructive pattern used to eliminate other harmful mental patterns. Once the mind is cleansed of its impurities, the song itself eventually dissolves into silence, fulfilling its purpose. Acharya Prashant emphasizes that while 'Bhajan' is a superior method, it is not the only one. Because human nature is complex and constantly changing, different spiritual practices like silence, action, listening, and physical challenges are necessary. He compares humanity to a patient requiring a variety of medicines, suggesting that multiple methods are needed to achieve the ultimate goal of liberation.
