yavan mano rajasa purusasya
sattvena va tamasa vanuruddham
cetobhir akutibhir atanoti
nirankusam kusalam cetaram va
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
As long as the mind of the living entity is contaminated by the three modes of material nature (goodness, passion and ignorance), his mind is exactly like an independent, uncontrolled elephant. It simply expands its jurisdiction of pious and impious activities by using the senses. The result is that the living entity remains in the material world to enjoy and suffer pleasures and pains due to material activity.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
In Caitanya-caritamrta it is said that material pious and impious activities are both opposed to the principle of devotional service. Devotional service means mukti, freedom from material entanglement, but pious and impious activities result in entanglement within this material world. If the mind is captivated by the pious and impious activities mentioned in the Vedas, one remains eternally in darkness; one cannot attain the absolute platform. To change the consciousness from ignorance to passion or from passion to goodness does not really solve the problem. As stated in Bhagavad-gita (14.26), sa gunan samatityaitan brahma-bhuyaya kalpate. One must come to the transcendental platform; otherwise life’s mission is never fulfilled.
