Everybody should have a knowledge of the workings of the mind: What are the Gunas? How do they operate? They should have a knowledge of the Vasanas, Subha Vasanas and Asubha Vasanas; and of the three states of consciousness–waking, dreaming and deep sleep, and also find out where the mind rests during these states. All these things are necessary. After that you should practise a little Yoga, Japa and concentration. It is then that you can have perfect mastery over the mind.

The mind wants supreme Delight, unalloyed Happiness, Bliss unmixed with pain. That you can attain only in the Atman. Jyotishamapi tat jyotih… hridi sarvasya vishtitam–The light is seated in your heart. Yo vai bhuma tat sukham–do not forget this Upanishadic Vakya. If you want supreme bliss, you can have it in the Bhuma alone, in the unconditioned Self which is beyond time, space and causation. Study psycho-analysis; become a great psycho-analyst, and then attain your goal of life, the realisation of Bhuma! -The above text is from the Introductory Notes.
