Once Khwaja Azizul Hasan (Raheemahullah) asked Shaykh Thãnwi (Raheemahullah);
“How will a person know that he has attained sainthood and has established a link with Allah? Will he realise that he has actually established a firm link with Allah? Will he perceive that Allah has entered his heart?”
Shaykh Thãnwi (Raheemahullah) replied,
“When you attained puberty (buloogh) did you realise it? Did you have to ask your friends, ’O friends! Tell me, have I attained puberty?” Shaykh Thãnwi (Raheemahullah) then explained;
Likewise, when a person devotes some time in the company of the Ahlullah (saints), engaging in Zikrullah and abstaining from sins, his soul reaches puberty. A different life enters in him. His heart becomes filled with the love of Allah and he perceives the special spiritual warmth and closeness of Allah.
