In the progression of Raja Yoga, the seventh limb is Dhyana, commonly translated as meditation.
If Dharana, or concentration, is the effortful struggle to hold the mind on a single point, Dhyana begins precisely where that struggle ends. The mind no longer has to be pulled back again and again; it starts to move on its own, smoothly and continuously. Swami Vivekananda offered a classic and beautiful analogy to explain this shift.
In Dharana, the mind is like water falling in drops. Each moment of focus is separate. The attention stays briefly, then slips away, and must be brought back with effort. In Dhyana, the mind is like oil being poured from one vessel into another—an unbroken, steady, perfectly smooth stream.
Following the ancient yogic texts, Vivekananda described this transition with a precise inner mathematics. Twelve seconds of completely unbroken focus constitute one Dharana. Twelve such Dharanas—about one hundred and forty-four seconds—become one Dhyana. When the mind can rest on a single point, such as the inner light of the heart, for roughly two and a half minutes without even a single flicker of another thought, concentration has ripened into meditation.
At this stage, a profound internal shift occurs. In the earlier limbs, you are sharply aware of yourself as “the meditator,” consciously working to hold attention. In Dhyana, that sense of “I am meditating” begins to fade. The mind becomes so absorbed in the object of meditation—whether a light, a sound, or an idea – that the body is forgotten, the surroundings disappear, and even time loses its meaning.
Vivekananda compared the mind in Dhyana to a piece of perfectly clear glass. Place a red flower behind it, and the glass appears red. In the same way, the mind takes on the exact quality of whatever it meditates upon, reflecting it without distortion.
This is why Vivekananda described Dhyana as the true “cooking” of the brain. He taught that deep, sustained meditation alters the very chemistry of the body. Physical energy is refined and converted into Ojas, spiritual vitality. The transformation is not merely psychological but physiological, which is why those who meditate deeply often radiate a quiet glow or a magnetic presence. Their brains, he said, have been reorganized by the power of uninterrupted inner flow.
