Mantras are the ancient Sanskrit rhymes discovered by great seers (saints) in various yugas. The words are scientifically arranged in such a way and the way these are recited in a specific tone – that it leaves a definite vibrational effect on its surroundings. These vibrations have got the capacity to manifest divine energies in the environment.
A word or a group of words in a mantra consists of certain Beeja Aksharas (seed letters) which have dormant powers associated with it and just like a seed when taken care grows into a tree, the beej mantras also start exhibiting their powers over a period of time after continuous practice.
As per an experiment the different types of sound vibrations are able to produce different types of images on sand. As Mantras are not just a simple arrangement of sanskrit words but scientifically discovered phrases by saints, the vibrations produced by recitation of it have a definite impact on our human body. It leaves a positive vibrations on our body chakras and helps in harnessing our psychophysical energy system. Repetition of these mantras systematically in a specific fashion for a period of time to achieve a goal is called Japa Yoga.
As per Hindu scriptures each mantra is associated with a devta (demigod) and is recited to attain a specific goal. Which mantra is suitable for a seeker- This decision is made by his Guru depending on his nature and his desired goals. When a mantra is passed on to a seeker by his Guru – it is not just a word but an inherent power associated with that word is also given. This power then is increased over a period of time by continuous practice of japa and helps seeker to get his desired goals.
There are four kind of Japa depending on how advance is a seeker in his practice. These are as follows:-
1. Vaikhari Japa: The seeker practice the japa by repeating the mantra loudly.
2. Madhyama Japa: The seeker although practice japa without making any sound but his lips movements are there.
3. Pashyanti Japa: In this kind of japa the seeker is at a very advance stage and even his lips movement are not visible as he practice the mantra within his self.
4. Para Japa: The seeker is at most advanced stage in this and the mantra is so deeply seated in his heart that even without his practice the vibrations of same are on in his self, leaving a positive effect.
Irrespective of the type of japa, it should be practiced with a lot of faith and devotion to get quick results. The power of Mantra will definitely leave its impact but it depends on the parameters like regularity, purity of mind, devotion, faith etc. There is no doubt that a person if practice japa yoga regularly with a pure mind and lot of faith and devotion will surely achieve his desired goals in a very short time.
