'Abir' and 'Gulal', yellow and red, nice colors, happy colors, auspicious. We sprinkle that on the lingam at the time of 'abhishekam'. Actually threads of two colors are made into one thread and that is bound on the wrist. Or the thread is rolled with kumkumam (roli). The following is the only karma-kandi chant (while tying the thread on the wrist) that I remember from my childhood:
"Yada badhnandakshyayana hiranyam shatanikayah sumanasya mana, tadma abadhname shat sharaddhyaya chobhayam lokaviram rakshasya me keshavah, twam jiva sharadam shatam."
Don't know if I have written it correctly. Also I do not know complete meaning.
