Saffron dust
Srimad-Bhagavatam
SB Canto 3
O my dear Vidura, the Lord's waist was covered with yellow cloth resembling the saffron dust of the kadamba flower, and it was encircled by a well-decorated belt. His chest was decorated with the śrīvatsa marking and a necklace of unlimited value.
SB Canto 4
Karmīs work day and night to improve their economic condition, jñānīs undergo severe austerities in order to get liberation, and yogīs also undergo severe austerities by practicing the yoga system for attainment of wonderful mystic powers. A devotee, however, is not interested in such activities; he does not want mystic powers or liberation or material prosperity. He is satisfied in any condition of life, as long as he is constantly engaged in the service of the Lord. The Lord's feet are compared to the lotus, wherein there is saffron dust. A devotee is always engaged in drinking the honey from the lotus feet of the Lord. Unless one is freed from all material desires, he cannot actually taste the honey from the Lord's lotus feet. One has to discharge his devotional duties without being disturbed by the coming and going of material circumstances. This desirelessness for material prosperity is called niṣkāma.
