“Cast X-ray eyes upon your own inferior nature. Introspect, and scrutinise your motives. Examine the factors that cause your outer behaviour, from the states and conditions of your mind,” Sivananda admonishes.
This guidance is given as a measure in the control of mind, because no man can easily acquit himself of the terrific havoc wrought in himself by the hidden animal impulses and common human emotions. Very strong cross-currents of likes and dislikes, love and hatred sway his mind. Secret longings and veiled desires destroy his happiness and ruin his peace and wisdom. Passionate impulses lurk somewhere in the crannies of his nature; ungratified wishes lie in wait for a gross manifestation and render his senses ungovernable, his circumstances unmanageable, his wisdom feeble. Understand this inner psychological nature, thoroughly. Survey it. Examine it. Scrutinise it. This examination is almost half the cure.
After a thorough grasp of the inner inferior nature that renders the mind so wild and unruly, fraught with the potentialities for errors and misery, sit not idly nor resign your will to fate. Start vigorous Sadhana right now. Throw out completely the whole of this inner dross. Bring about a radiant transformation of the entire inner nature. Sivananda says, “A fanciful interest in the spiritual path is of no use. Take recourse to dynamic and many-sided Sadhana.” Sivananda says, “Relentless effort to live a spiritual life is very necessary. The angle of vision has to be changed. Regular Sadhana will keep the mind always clean and conquered.”
