In plain words
We must set about giving up this feeling of the non-Self.
Pārvatī's tapas
We must not depend on worldly strength and ability. God accepts only purity of the Ātma; He does not yield in the least to worldly efforts. In the Viṣṇu Purāṇa and in the Śiva Purāṇa alike, Pārvatī is famed as supremely beautiful in all the world. Fancying herself so beautiful, she made many efforts, full of Ahaṅkāra, to win Śiva over by her beauty. For all the efforts she made, she failed in them. Recognising this truth, she humbled her Ahaṅkāra and made her body undergo many kinds of tapas. Dried by sun and wind, drenched by rain, shivering in the cold, she went through hardships of every kind and wasted her body away. But her mind she fixed on Īśvara alone. Then Īśvara, seeing that her Ahaṅkāra had been rooted out, told her to remain as His other half, as half of His own body. So what does this mean? Prakṛti is Pārvatī. This Prakṛti is supremely beautiful. Such beautiful Prakṛti indulges in many kinds of pride and draws everyone to herself. Because she wins everyone's admiration, her pride grows greater still.
There is one Doer of all
Every man born into this Prakṛti spends his life full of Ahaṅkāra. Pride of youth, pride of learning, pride of wealth, pride of beauty, pride of strength, pride of power: there are many, many more kinds of pride besides. Pride of learning drives God very far away. No one who has fallen prey to such pride becomes fit to attain Divinity. Only those without Ahaṅkāra are the ones who attain Divinity. Vālmīki, Nanda, Kucela, Vidura, Hanumān, Tinnaḍu, Śabarī and all such were free of Ahaṅkāra. They were wholly devoted to the Lord. So in this physical world we have no power of any kind. All that is seen here is impermanent. It does not last. We grow many kinds of pride and fall to ruin. Give up the notion of doer, deed and doing, and recognise this truth: there is one Doer of all. The giver is He, the receiver is He, the thing given is He. When all is a divine feeling, where can there be a second thing? “The universe is the form of Viṣṇu”, “All this is indeed Brahman”: we must develop such a feeling of oneness.
