Good people sacrifice their personal interests and purify the atmosphere of their environment. They are like an incense stick which goes on burning and radiating fragrance to everyone who comes close to them, even while burning themselves out. One who always thinks of others, of helping others, harbouring sacred feelings in mind, will be improving day after day. A person endowed with sacred qualities can be compared to a man who builds a wall. The man who builds a wall will continuously climb up and he will never climb down. On the other hand, individuals who are always causing trouble harm and hurt to others, who are jealous of the prosperity of others, can be compared to the persons who are digging a well. The persons engaged in digging a well will continuously descend lower and lower while the persons who are building a wall will ascend higher and higher. (SSB 1973, pp. 224-225)
