The rasa (sentiment) in the line 'धरिला पंढरीचा चोर गळा बांधुनिया दोर' is भक्ति (Devotion) and वात्सल्य (Vatsalya - Parental Love).

Explanation:

• भक्ति (Devotion): The line expresses intense love and devotion towards Lord Vithoba of Pandhari. The act of 'catching the thief' and 'tying him with a rope' is symbolic of the devotee's complete surrender and intimate connection with the deity.
• वात्सल्य (Vatsalya - Parental Love): The line also carries a sentiment of parental love. Treating God as a child who needs to be disciplined and cared for is a common expression of Vatsalya Bhava in devotional poetry. The devotee assumes the role of a parent lovingly restraining and cherishing the divine child.

Although seemingly contradictory, these rasas often coexist in devotional poetry to express the multifaceted relationship between the devotee and the divine.
