What do we learn from our Hussayni rituals?!

"One day, Lady Fatima Az-Zahra (peace be upon her) asked her father the Messenger of Allah (Allah's prayers be upon him and his holy Household): Father, in which time my son Al-Hussayn will be killed? he answered: In a time where neither me, you, his father or his brother will be present. She said: Father, Who will bury Al-Hussayn? and who will cry for Al-Hussayn?
The Messenger of Allah (Allah's prayers be upon him and his holy Household) then said: Gabriel informed me that followers [shiites] and lovers were created for Al-Hussayn, they bury Al-Hussayn, set funerals of Al-Hussayn and cry for Al-Hussayn."
Praise to God, nowadays, these rituals are commemorated by millions of believers in various parts of the world, so me must learn from them:
First: upholding the word of God, enjoining good and forbidding evil.
Second: Recalling what happened to Ahl Al-Bayt (peace be upon him), nourishing the emotions by the will of resistance and defiance.
Third: Documenting the march of the Mohammadian approach and the seal of messages.
Fourth: Informing, educating and consolidating the true Islamic values in the same community.
Fifth: The education shown in words and deeds.
Sixth: preparing and mobilizing to confront the enemies of humanity.
Seventh: Alarming and warning of the most despicable of people, the progeny of Hind the eater of livers.
Eighth: Exposing the juggernaut tyran and the unjust ruler.
