THE ENVIOUS ARE NOT AT PEACE
Dadati ve yatha saddham yatha pasadanam jano
Tattha yo manku bhavati paresam pana bhojane
Na so diva va rattim va samadhim adhigacchati.
People give according to their faith and as they are pleased.
Whoever therein is envious of others' food and drink, gains no peace either by day or by night. 
THE UNENVIOUS ARE AT PEACE
Yassa c'etam samucchinnam mula ghaccam samuhatam
Sa ve diva va rattim va samadhim adhigacchati.
He who has this feeling of displeasure cut off, uprooted and destroyed, gains peace by day and by night. 
Tissa, a young novice, had a very bad habit of disparaging other people's good deeds. He even criticized the gifts given by such renowned donors like Anatha Pindika and Visakha. Besides, he boasted that his relatives were very rich and were like a well where anyone could come for water. Hearing him boast thus, other bhikkhus were very sceptical and they decided to find out the truth.
Some young bhikkhus went to his village to investigate. They found out that Tissa's relatives were all poor and that all this time Tissa had only been boasting. When the Buddha was told about this, he said 'A bhikkhu who is unhappy with others receiving gifts and offerings can never attain Insight.'
