Acharya Mahaprajna
Psychological distortions such as cruelty, retaliation, hate, fear etc. have their origin in the unbalanced and unregulated secretions of adrenals and gonads. They generate negative attitudes and irrational behaviour and result in psychic uncleanliness. It is therefore obvious that to cleanse the psyche, we have to regulate the endocrine output and eradicate distortions from our mental tendencies and behaviour.
Perception of the whole chain of psychic centres can modify the synthesis of the endocrine output and weaken the intensities of impulses and urges, thus making them controllable by the conscious mind.

Exercise:
Maintaining the relaxed condition of the body and the motionless posture, commence the perception of psychic centres. Focus your attention on (I) Sakti Kendra—Centre of Energy—and be aware of the vibrations produced by the flow of vital energy in this psychic centre, for 2 to 3 minutes. Repeat the exercise by focusing the attention respectively on:
| 1 | Shakti Kendra | Centre of Energy |
| 2 | Svasthya Kendra | Centre of Health |
| 3 | Taijasa Kendra | Centre of Bio-Electricity |
| 4 | Ananda Kendra | Centre of Bliss |
| 5 | Visuddhi Kendra | Centre of Purity |
| 6 | Brahma Kendra | Centre of Celibacy |
| 7 | Prana Kendra | Centre of Vital Energy |
| 8 | Caksusa Kendra | Centre of Vision |
| 9 | Apramada Kendra | Centre of Vigilance |
| 10 | Darsana Kendra | Centre of Intuition |
| 11 | Jyoti Kendra | Centre of Enlightenment |
| 12 | Santi Kendra | Centre of Peace |
| 13 | Jnana Kendra | Centre of Wisdom |
and be aware of the vibrations produced by the flow of vital energy in each centre for 2 to 3 minutes. It should be remembered that after meditating on the nether centres (#1,2,3), it is essential to meditate on the higher centres. The order of meditation is normally upwards, and not downwards.
If there is not enough time to cover all the centres, the nether ones may be left out.
