Kṛṣṇa gives the beautiful and famous analogy of the lotus leaf. He says that anyone who performs their duty without attachment, surrendering all results to the Supreme, is untouched by sinful reaction, just as a lotus leaf is untouched by water. The lotus leaf grows in the mud and sits on the water, yet it remains perfectly dry; water simply beads up and rolls off its surface. Similarly, the yogī lives in the ‘mud’ of the material world and performs the ‘water’ of material actions, but his consciousness remains dry and pure. He doesn’t let the world stick to him. The secret is ‘brahmaṇy ādhāya’—giving the results to God. If you are a courier delivering a package, you don’t worry about the contents or the value; you just deliver it. Arjuna is being told to deliver his actions to Kṛṣṇa. By doing so, he becomes immune to the ‘wetness’ of sin and guilt that he so fears. His soul will remain as pristine as a lotus leaf in a lake.
