Concept:
In Yoga philosophy, especially in the Patanjali Yoga Sutra, liberation is attained when the distinction between Purusha (pure consciousness) and Buddhi (intellect or higher mind) becomes fully realized and purified.
The state in which Buddhi becomes completely pure and reflects Purusha without distortion is called “Kaivalya,” meaning absolute isolation, liberation, or independence of consciousness.
Step 1: Understand the meaning of Buddhi and Purusha.
• Purusha represents pure witnessing consciousness.
• Buddhi represents intellect or discriminative faculty belonging to Prakriti.
Due to ignorance, Purusha appears connected with mental activities. Through Yoga practice, Buddhi becomes purified and transparent.
Step 2: Understand the result of purification through Samānbhāva.
When Buddhi and Purusha attain purity and equilibrium (Samānbhāva), the false identification between consciousness and material nature ends.
This ultimate liberated state is called:
\[
\text{Kaivalya}
\]
Kaivalya means:
\[
\text{Absolute freedom or liberation of Purusha}
\]
Step 3: Analyze the given options.
Option (A): Bandhan
Bandhan means bondage, which is the opposite of liberation.
Option (B): Kaivalya
Kaivalya is the final liberated state attained through purification and discrimination between Purusha and Prakriti.
Option (C): Samadhi
Samadhi is a deep meditative state, but Kaivalya is considered the ultimate goal beyond Samadhi.
Option (D): Chittparikarma
Chittparikarma refers to purification or cultivation of the mind and is not the final liberated state.
Step 4: Identify the correct option.
Since purification and equilibrium of Buddhi and Purusha lead to liberation, the correct answer is:
\[
\boxed{\text{Kaivalya}}
\]
