Dhyana(Meditation) Yoga forms the seventh constituent or limb of the ancient science of Yoga. It is derived from the Sanskrit root "dhyai" which means, "to think of". The literal meaning of Dhyana is Meditation. It concentrates upon a point of focus, with the intention of knowing the truth about it and is the thought and meditation of spiritual things. While practicing Dhyana Yoga, we meditate on a single flow of idea. The purpose is to withdraw all senses from various objects of interest. The focus is laid upon on one object. This is a next step of Dharana. In this concentration on one object is steadier and for long time than Dharana.
                      Dhyana Yoga produces a state of tranquility. Its objective is to cleanse the subconscious, develop concentration, clear the mind, and bring about various stages of unified communion with God. Practicing Dhyana Yoga allows the person to calm his mind and allow him/her to look at the outside world without any distractions. This enables him/her to reach a heightened level of awareness. Meditation, consciousness, and experience, are all but a single unity. There are different forms of Dhyana Yoga and it is very important to remember the three things given below.

One-pointedness of mind is the first thing that means controlling its movements.Secondly, setting bounds to one's life to help achieve this, this means doing actions after weighing and measuring them.The third thing is the evenness of vision or state of level- headedness, which means having the nobility and decency to think in terms of the whole world.
