दशेशत्रोररिगेहभाजो लग्नेशशत्रोरपि वाऽथ भुक्तौ । शत्रोर्भयं स्थानलयः तदास्य स्निग्धोऽपि शत्रुत्वमुपैति नूनम् ॥ २८॥
During a planet's Dasa-period, when a Bhukti of a planet inimical to the Dasanatha, or of a planet occupying the 6 th house (or an inimical house) or of a planet inimical to the lord of the Lagna is in progress, the native concerned will have to apprehend danger from his enemies, and loss or change of position; even the person who has all along been friendly will turn out hositile to him.
