We all have hearts. Our job is to keep our hearts pure. Life is about keeping your heart pure. The greatest impurity is pride. Pride is worse than cancer. Initiating salaam is one cure for pride. One point to note is that the salaam has to be a sincere salaam.
“The aim of Tasawwuf is to clean the heart from spiritual diseases, and to educate, or transform, the self (Nafs), and to seek Allah Subhanahu Wata’ala’s pleasure through imposing the Shariah on ourselves inwardly and outwardly, all in the way followed by our Rasulullah Sallalahu Alayhi Wasallam and the righteous predecessors (Salaf).”
