Question: How can kids be taught the Third & Fifth Precept, of abstaining from sexual misconduct and taking of intoxicants?
Answer: For teaching the Third Precept to kids who have yet to reach puberty, I suggest teaching it ‘forward’, simply in terms of loyalty to their friends and future spouses. In terms of physicality, I suggest teaching it in terms of abstaining from sensual (instead of sexual) indulgence (of the senses). Sex just happens to be the melting pot of sensual enjoyments. Eg. see tinyurl.com/bealamp6 page 76′s last paragraph:
‘Aware of the suffeing caused by sensual indulgence, I will also not mindlessly indulge my senses of sight, hearing, smell, taste, touch and/or mind in the sense pleasures (e.g. shows, music, food, sex etc.) such that I am distracted from the path of self-improvement.’
You can also remind them likewise that substances addicted to cause suffering when deprived, leading to loss of mindfulness, which is dangerous to oneself and others, as one might come to break all the other precepts. This is classically represented by this story: http://groups.yahoo.
