What would you include if you had to make a suggestion. Please include subcategory. If it is not a Buddhist book please write a short description.

I sold all my Buddhist books but you might like Triptimine Palace by James Oroc.

Old path White clouds, by Thich Nhat Hanh

I've read a few dhamma books. During the reading of the following books I gained insights that made sense to me. 


-Ajahn Chah

• Food for the Heart
• Being Dharma 

-Ajahn Brahm

• The Art of Disappearing
• Mindfulness, Bliss and Beyond

-Walpola Rahula

• What the Buddha Taught

-Shaila Catherine

• Focused and Fearless
• Wisdom Wide and Deep

-Leigh Brasington

• Right Concentration

-Bhante Henepola Gunaratana

• The Mindfulness in Plain English Collection
• Journey to Mindfulness
• Loving-Kindness in Plain English

-Bhikkhu Bodhi

• In the Buddha's Words
• The Eightfold Path

-Ayya Khema 

• Be an Island
• Being Nobody, Going Nowhere 

I would also include the website of Thanissaro Bhikkhu. He has a lot of free dhamma books that he hosts on the site. They are all very good.
