न हि देहभृता शक्यं त्यक्तुं कर्माण्यशेषतः ।यस्तु कर्मफलत्यागी स त्यागीत्यभिधीयते ॥
na hi dehabhṛtā śakyaṃ tyaktuṃ karmāṇyaśeṣataḥyastu karmaphalatyāgī sa tyāgītyabhidhīyate
Nor indeed can embodied beings renounce all works; verily he who gives up the fruit of action, he is said to be a renouncer.
Gītā 18·11The essence of renunciation, the true Tyaga, the true Sannyasa is not any rule of thumb of inaction but a disinterested soul, a selfless mind, the transition from ego to the free impersonal and spiritual nature. The spirit of this inner renunciation is the first mental condition of the highest culminating sattwic discipline.
