Purify the mind fast, through the practice of right conduct, and then take to the practice of concentration. Concentration without the purity of mind is of no avail. Concentration will be intense if all distractions are remove. During this process of concentration if the mind wanders from the object, bring it back again. Repeat this process as long as possible.
Meditation is the process of using our mind to establish communication with our inner-self.
To do meditation, one needs an undisturbed environment. Although, as Amma said in Her Oracle to let the mind wander and watch it go, we need an environment that would not disturb the mind from wandering within. Set apart a room or a place for doing meditation. This place should be clean, tidy and without any physical disturbance. Maintain absolute silence.
