Step 1: Understanding Chitta Bhūmis.
In Yogadarshana (Yoga Philosophy of Patanjali), Chitta (mind-stuff) is described in terms of different levels of functioning known as Chitta Bhūmis.
Step 2: Types of Chitta Bhūmis.
There are five main states of Chitta: Kṣipta (restless), Mūḍha (dull), Vikṣipta (distracted), Ekāgra (one-pointed), and Niruddha (fully controlled).
But in this question, four stages are specifically highlighted: Kṣipta, Mūḍha, Vikṣipta, and Ekāgra.
Step 3: Correct Order.
- D. Kṣiptaḥ = Restless state of mind (first stage).
- C. Mūḍhaḥ = Ignorant/dull state (second stage).
- A. Vikṣiptaḥ = Distracted mind (third stage).
- B. Ekāgraḥ = One-pointed mind (final stage before Niruddha).
Step 4: Conclusion.
Thus, the order is D, C, A, B.
