After Putana died her body was burned, and its pleasing fragrance spread for miles. This phenomena is described by Srila Prabhupada as follows: “When Putana was somehow or other, directly or indirectly, induced to render some service to the Lord by feeding Him with her breast, she was immediately purified, so much so that when her nasty material body was burnt to ashes, it gave off the fragrance of aguru, the most agreeably scented herb.” (Srimad Bhagavatam 10.6.34/part of the purport).
