avāpsyasi

अथ चैत्त्वमिमं धर्म्यं संग्रामं न करिष्यसि

avāpsyasi — will incur

But if you will not fight this rightful battle, you abandon your own duty and your good name, and you take on the wrong instead.

सुखदुःखे समे कृत्वा लाभालाभौ जयाजयौ

avāpsyasi — shall incur

Treating pleasure and pain alike, gain and loss, victory and defeat — then engage in the fight, and you take on no wrong.

श्रुतिविप्रतिपन्ना ते यदा स्थास्यति निश्चला

avāpsyasi — you will attain

When your understanding, no longer pulled about by scripture, stands still and steady in itself — then you will have reached yoga.

अभ्यासेऽप्यसमर्थोऽसि मत्कर्मपरमो भव

avāpsyasi — you shall achieve

If you are unable even to practise, then make my work your highest aim. Doing what is to be done for my sake, you will reach perfection.
