Hazrat Shaikh Moulana Muhammad Zakariyya (rahmatullahi ‘alaihi) mentioned:

In this era the Mashaayikh do not emphasise upon their disciples to make a lot of sacrifices. Though, when I was young, I used to see many pious people and Mashaayikh labour hard and render great sacrifices for deen. However, in this day and age, an easy prescription that we are taught is to focus towards the reformation of our hearts. One should protect one’s heart from sin and not allow his heart to be distracted and diverted from the obedience and remembrance of Allah Ta’ala. At all times one should protect his heart. (Malfoozaate Hazrat Shaikh 1/110)
