Couplet 518-522

خفتہ آں باشد کہ اُو از ہر خیال

Sleeping is the one who has thoughts

دارد امید و کند با اُو مقال

Association with it and discusses about it

نے چناکہ از خیال آید بحال

He is not the one to come to ecstasy from thoughts

آں خیالش گردد اُو راصد ا بال

Rather those thoughts would bring hundreds of troubles

دیورا چوں حور بیند اُو بخواب

He is seeing satan as beauty in the dream

پس ز شہوت ریزد اُو با دیو آب

And then cohabited with it

چونکہ تخمِ نسل در شورہ بریخت

As soon as he puts seed in the earth

اُو بخویش آمد خیال از وے گریخت

He comes into senses and comes out of it

ضُعفِ سر بیند ازان و تن پلید

Due to this, he feels weakened in mind and impure in body

آں ازاں نقشِ پدیدِ نا پدید

Ashamed of the external & perishable picture

                       The two types of alertness (بیداری) has been explained in the previous couplets, one is alertness of body, which is contemptible and the pollution of thought due to this has been narrated. The second is alertness towards Allah, which is likeable. There are two categories of sleep, one is sleep in respect the worldly affairs, which is likeable, and the other is sleep in respect of Allah, which is contemptible. These two categories have been detailed in these following couplets, as the excellence of attributes of sleep and condemnation of thoughts, which are there in our writings, is not for absolutely for all the sleeps and similarly not for condemnation of all the thoughts. Instead the thoughts of sleep towards worldly affairs are beneficial and thus those are different likeable thoughts that every such thought leads for his desire for hope for wusool Allah. And such thoughts seem to be discussing with him  i.e. pious thoughts  and care of heart is also the medium for wusool-il-Allah and the inspiration, knowledge and the truth inculcate in the heart, since these thoughts are the reason for such knowledge and truths, thus these are metaphorically termed that these thoughts are in discussion with him, as is there in this Ayaah of Quran (30:35) –

Or have We sent down to them an authority, and it speaks of what they were associating with Him?

                      And not those sleeps and thoughts, which stresses and are contemptible, as one feels ashamed and  are troubles for him, when he comes back to his original stage of alertness (بیداری). These are those thoughts of worldly affairs which when happened brings a lot of joy and taste, but would be nothing except sins and troubles at the time of original alertness (بیداری) i.e. at the time of death. There is such an example of this sleep and this thought like a person considers satan as a beautiful girl in the dream or thought and then cohabit with her and see it dropped in the ground and wasted. At that time, his thoughts and senses come back and the imagination of the girl disappears, then he feels weak in the head and body becomes impure. Now he regrets, as to how that imagination of the girl happens and how it disappears, as her existence was only in thoughts and imagination and same is the situation of the seekers of other than Allah.
