विभेषि यदि संसारान्मोक्षप्राप्तिं च काङ्क्षसि ।
तदेन्द्रियजयं कर्तुं, स्फोरय स्फारपौरुषम् ॥
If you are afraid of samsara and desire the attainment of moksha — then to conquer the senses, rouse your fullest heroic effort (sphara-paurusham).
The vasana (longing) for freedom must arise — and with it, the extreme effort and striving. Like the caged lion who has glimpsed freedom: the vasana includes both the longing and the full-body commitment to achieve it. The five senses — shabd (sound), rupa (form), rasa (taste), gandha (smell), sparsha (touch) — their limitless desires must be restrained. Do not fulfill the desires as they arise. Make the firm sankalpa to not fulfill them. And if countless dukhas must be faced — learn to bear them with a smile. Develop the atma-shakti to endure dukha-dard. Luck cannot be relied upon. Time cannot be used as a pretext. Bhagiratha purushartha alone works.
The simple version: Fear of samsara and desire for moksha are not enough. They must become paurusha — heroic effort to conquer the senses. No vasana, no effort, no result. The bell of mahapurushartha must be rung with mana-vachan-kaya.
