Premanand Maharaj Ji
क्या सब भाग्य में लिखा है, फिर मेहनत क्यों करें?
भाग्य के भरोसे आलस्य नहीं, पुरुषार्थ
The human birth is given for purusharth (effort). "Whatever will be, will be" is a lazy, negligent nature, and such beings do not find welfare.
In a lazy, negligent nature one thinks 'whatever will happen will happen.' Such negligent beings do not attain welfare. One must make great effort.
