“Don’t tune to that channel. It’s not very decent.”
“Don’t chat on computer for too long. It wastes your time.”
“Don’t buy that cheese. It’s made in Denmark.”
“Don’t listen to that music or Don’t watch that movie. It’s not for you.”
“Don’t wear this dress. It’s too revealing.”
“Don’t smoke and don’t drink that stuff. It’s not allowed.”

These ‘Do’s” and “Don’ts” don’t help much because its just like ignoring the roots and cutting the branches off.
What needs to be seen is that why people involve in these acts and how can they be helped. How does human mind work. How does it learn and perceive from it’s surroundings and then what makes it decide what is to be adapted and what to be rejected, even though it’s obviously constructive or visibly harmful.

The Divinity claims that it has ordained the awareness of Good and Evil within human being. Qur’an. Chap 91:8; 87:2. Hence unless one has tainted oneself, this light from within will remain there in order to distinguish right from wrong.

Apt education involves keeping this light integral, protecting it from the external effects which can waft it off for example by preferring desires over duties or by keeping one’s ego ahead which could lead to specious hatred or love;

Second entity in this regard which can help towards a precise approach in life helping prevent harm to self and others, is the knowledge from the Divine sources that came to us through His selected people called Prophets and the Divine Books that were revealed to them. Instead of getting used to and following blindly the chronicles we hear around ourselves from childhood through adulthood and then old age, we need to struggle in order to find the Truth in it’s purest appearance. This world is built upon the corporeal law of “Struggle and Reward” & “Cause & Effect” and one cannot expect this rule to be altered in this particular matter of Guidance in life.

Hence unless this core which entails the protection and resumption of the inner light or guidance and the knowledge from the Revelations is looked after well and kept alive, trying to stop people from performing certain acts that can be classed as detrimental or evil, is less likely to help. The effort has to originate from the correct base, into the accurate direction, that is, from the roots to the branches, not the other way round because the physical laws of the Creator will rebuff this order.
