'Vision of the eye' (Ra'y al-'iyan) refers to the witnessing of the physical, seeing eye.

'In certainty' (Yaqinan) means in absolute reality, without doubt or suspicion."

In his poem titled 'I Searched with My Secret' (Bahathtu bi-Sirri), he says:

Seven stars and four,

They have a Crescent appearing in China.

His saying 'They have a Crescent appearing in China': He refers to the Meaning (al-Ma'na), and 'China' (al-Sin) refers to the Gate (al-Bab).

(The expression of al-Dardad al-Halabi):

His soldiers are the Bees; whoever stays with them

Shall find repose in Spirit and Fragrance.

'His soldiers' refers to His followers, His party, and His Shia; the pronoun [His] refers to the Crescent (al-Hilal). 'The Bees' (al-Nahl) are the Believers.

I drank the Pure Water (Ma' al-Ma'in) from Him

and thus I was never stingy with [sharing] the vessel thereafter.

The pronoun in 'from Him' refers to the Crescent whose soldiers are the Bees... etc.
