In plain words
They give rise to many illnesses in man. It ruins the digestive system. It keeps the heart's circulation of the blood from running its proper course. It brings on blood pressure. Diabetes sets in. Through mental worry, illnesses of a mental kind arise. Illnesses of the lungs arise. That is, the saṅkalpas that are the root cause of illness stand in the way of man's Ānanda. Every human being longs: “I must have Mukti.” Who needs this Mukti? Does the body need it? Does the mind need it? Or does the Buddhi need it? Or do the senses need it? If one inquires so, all of them need Mukti.
Attaining Śānti is Mukti
To be released from illness is itself release. For Śānti to enter man and release him from unrest is Mukti. For a man suffering from hunger to eat food and release himself from hunger is Mukti. Whatever removes each hardship, each pain in daily life, is Mukti. First of all, we must experience the Muktis we are meant to experience while living. To think that Mukti is gained after death is a great mistake. The Muktis we have to achieve today are physical ones. So long as there is attachment to the body, there is no escaping any of these. The karmas man undergoes today are negative too. So long as these negative thoughts are in man, he gains no Śānti at all. The Mukti we must attain is Śānti itself. Once we gain Śānti, it is as though we had gained everything. God means Brahman itself. Brahman means Satya itself. Satya is the very form of God. Only when we travel on the path of Satya do we gain Śānti. Because these negative thoughts enter man, he falls prey to many kinds of unrest. With negative thoughts kept in the heart, however many prayers one offers, however many sādhanas one practises, however many pūjās one performs, all of it is in vain. The antaḥkaraṇa is a big water tank. All the actions we do, all the senses, are like taps.
