Material desires in the mind are the trash of material contamination. By such contamination, the living being is faced with so many compatible and incompatible things that discourage the very existence of spiritual identity. Birth after birth the conditioned soul is entrapped with so many pleasing and displeasing elements, which are all false and temporary. They accumulate due to our reactions to material desires, but when we get in touch with the transcendental Lord in His variegated energies by devotional service, the naked forms of all material desires become manifest, and the intelligence of the living being is pacified in its true color. As soon as Arjuna turned his attention towards the instructions of the Lord, as they are inculcated in the Bhagavad-gītā, his true color of eternal association with the Lord became manifest, and thus he felt freed from all material contaminations.
