Para vidya, as the knowledge of the Self through which the immortal is known. The self is the source of all beings. It is eternal, all pervading yet subtle, imperishable, unseen and unknown. Para vidya takes one towards Absolute by ensuring purity of mind. The experience of gaining and parting with material things is painful. The enjoyment obtained through them is very short and unreal. The fleeting pain and pleasure makes one aware of the drawbacks of apara vidya. A sincere seeker looks for something that is free from all limitations.
