1 Gita Sloka  Every Day - Chapter 18 - Moksha Sanyasa Yoga - Sloka 4

Harathi at Brindavan

Nischayam shrunu me tatra tyage bharata sattam I

Tyagah hi purusha vyaghra trividhah sam prakrititah II sloka 4

निश्चयं शृणु मे तत्र त्यागे भारत सततं I 
त्यागः हि पुरुष व्याघ्र त्रिविधः सं प्रकृतितः II श्लोक 4

Learn from the truth about this abandonment, O best of the Bharatas; abandonment, verily, O best of men, has been declared to be of three kinds

This has already been described in Chapter 3, sloka 30. To mention briefly again, the three kinds of tyaga are : 1. Phala tyaga - giving up the fruits like swarga, which result from doing karma or acts; 2. Karma tyaga - giving up the sense of possession in the works or karma ie. giving up the feeling  "These works or acts belong to me, because they are the means for attaining fruits which also belong to me"; 3. Kartrutva Tyaga - Giving up the feeling that he is the doer of the karma; and realising that the Lord indeed gets the work done through him. 

The goal of the jivatman is to be emancipated from prakriti which expresses itself in the form of karma. But he cannot and should not violently snatch himself away from karma. There is a natural and delightful way of transcending it. This is explained further
