Al-Qanduzi, the Hanafite narrator of traditions, in his radiant collection Yanabi' al-Mawadda (lit. Fountains of Constant Love) narrates a tradition from Abu Dharr al-Ghiffari who narrates from the Holy Prophet (s):
'The similitude of my progeny among you is that of the ship of Noah ('a); whosoever boards it is saved, and whosoever lags behind would perish'
The ship of al-Husayn ('a), however, according to another tradition is more rapid: Once a companion of Imam al-Sadiq ('a) asked him about the prophetic tradition
"Surely al-Husayn is the lamp of guidance and the ship of salvation" saying: "Aren't you [the Ahl al-Bayt ('a)] ships of salvation [too]?" The Imam ('a) replied:
"All of us are ships of salvation, save that the ship of al-Husayn ('a) is more spacious and faster.

With this in mind, the book 'The Sacred Effusion' authored by Sh Muhammed Khalfan gives an insight into Ziyarat e Ashura, which is a salutation presented to the master of the martyrs- Imam Hussayn (a.s)
This book, is very well written and provides a deep understanding of the ziyarah and if put into practice can establish a deep connection with the Imam (a.s)
The late mystic-scholar Ayatullah Mirza Tabrizi in his monumental prayer manual al- Muraqabat says:
'It should be known that the door of al-Husayn ('a) is the door of comprehensive mercy, rapid response and approval....'
A must read for anyone who wants to enjoy the spiritual bounties provided by Imam al Hussayn (a.s)
