Unwholesome thoughts at the time of death

> Say one reflects on the beauty of one's children, the beauty of one's husband or wife, the beauty of one's house or garden, or the beauty of a flower, and other such things: that is rooted in greed and delusion. It is a perverted perception (*sañña-vipallāsa*), based on unwise attention. If one has habitually looked upon such objects with such unwise attention, it will be very difficult at death suddenly to reflect upon them with wise attention. ...If one dies with such consciousness (rooted in greed and delusion,...) one cannot avoid being reborn in a woeful state. Quoted from the book "The Workings of Kamma" by The Most Venerable Pa-Auk Sayadaw. My question: so should we not reflect on the beauty of something? It's not a bad karma, right? So I thought it will just create attachment (that bounds us to samsara), but I didn't think it would lead to a rebirth in the lower realms? P.S it's not that I have doubts about this book, I'm just a little confused and need some explanation.
