They were using certain mystical terms among themselves in order to convey information.
اصطلاحاتی میان هم‌دگر ** داشتندی بهر ایراد خبر
The vulgar have learned this birds' language and (by means of it) have acquired prestige and authority.4010
زین لسان الطیر عام آموختند ** طمطراق و سروری اندوختند

Where is the Solomon who knows the birds' song? The demon, though he seize the kingdom (of Solomon), is an alien.
کو سلیمانی که داند لحن طیر ** دیو گرچه ملک گیرد هست غیر

دیو بر شبه سلیمان کرد ایست ** علم مکرش هست و علمناش نیست
Inasmuch as Solomon was rejoiced exceedingly by (the favour of) God, he had a birds' language (derived) from we have been taught.

The home of the Símurghs is beyond (Mt) Qáf: it is not (like) a hand-loom (easily accessible) to any imagination,
جای سیمرغان بود آن سوی قاف ** هر خیالی را نباشد دست‌باف

جز خیالی را که دید آن اتفاق ** آنگهش بعدالعیان افتد فراق
Not a parting that involves severance, (but a parting) for a wise purpose; for that high estate is secure from every (real) parting.
نه فراق قطع بهر مصلحت ** که آمنست از هر فراق آن منقبت
