Human being has always been attempting to seek eternal peace, happiness and joy; he feels that these can be achieved through the collection and use of material objects. This is correct as he can get momentary enjoyments from the use of these illusory material objects and probably that is the reason why he keeps on accumulating and using these material objects. It will not be wrong to say that material life is like a mirage which keeps on beckoning man to go after. He does not know that real peace and happiness is not outside but inside him only.
As a matter of fact real peace and happiness does not have any form or any definite place where it can be found. This is achieved through the knowledge of the Self for which the causeless grace of Gum and God is required. Therefore, one must have a highly accomplished Siddha Guru. Such a Guru or a great person awakens Kundalini-dormant power of the inquisitive sadhaka through the phenomenon of Shaktipata; this is done keeping in mind the capabilities of the sadhaka. Continuance of sadhana takes the sadhaka to the next stage after the awakening of Kundalini and that is the purification of five vital airs and five sheaths and then piercing ness of the chakras takes place; this makes the mind and chitta steady and subsequently the sadhaka starts experiencing peace and happiness. Further continuance of sadhana takes the purification to final stage, desires are over by then and the sadhaka realizes the Self.
Speaking and writing the whole process is so simple and easy but carrying it out is very difficult. Sometimes completion of this process requires many lives of sadhana but if sadhaka is fortunate to have the causeless grace of some saint, he may realize the aim in this life itself, There is no prescribed technique to earn this grace. This depends merely on the saint; he may oblige anybody. Yes, but the seeker must keep on working bard to can the grace of the saint. Even for doing hard work, grace of Guru or guide is required. This is why it is said 'Guru Kripa Hi Kevalam' i.e. it is the grace of Guru which gets you everything.
Some people have complained that their minds wander while sitting in meditation. What can be done to make the mind concentrate? There are many techniques for solving this problem and you may choose the best suited to your nature. While sitting in meditation, you may put your mind to work. If you are an idolater and your Ishta is Lord Rama, Krishna, Shiva or any other you may engage your mind in changing you to the form of your lslita. This can be likened to the dress rehearsal on a dramatic stage of your conscience. You may consider yourself in the form of Ishta and thus keep yourself in the pleasing mood. In this way, mind will become busy in changing you to the form of Ishta and will not wander anywhere and after the form is ready it will keep looking for that form. In another technique you may consider yourself to be a beam of light and keep on looking at the light rays. The easiest technique is to keep a watch on the incoming and outgoing breath. If some sadhaka has reached the stage of listening to 'Anahat Nada' inside the body he may keep his mind busy in listening to that sound. 11.0 these techniques fail in making the mind busy sadhaka may pray to Sadguru saying 'Oh Sadguru! I have no idea what to do to concentrate my mind. Please help me in getting what is most beneficial for me.'

It is not necessary that all the sadhakas may have experiences during meditation but those who have had them should know their esoteric meanings. Factually speaking, everybody's experiences are singular and uncommon so much so that any two sadhakas do not have common experiences. However, these experiences can be classified in three general classes-functional, perceptual and subtle internal experiences. Functional : rumbling sound in the abdomen during meditation is caused by the movement of air in that area. This is the activity of Prana-Apana there and takes place as desired by Sadguru, You cannot cany out such an activity by your own efforts. During the course of meditation some sadhakas make fore and back movements, few of them even fall down on the ground. This is Sahaja kriya yoga. Sadliakas should not even be touched. They will rise by themselves when they come out of meditation. If it is essential to raise them up, 'Jai Guru Datta'
Jai Guru Datta' should be spoken a few times loudly near their ears without touching them They come out of the meditative state in a few minutes. Some sadhakas hear musical sounds of clock, bell, conch, drum, and flute during meditative state. They should not be perturbed by this sound, this is Anahata Nada. In some cases upper half of the body of the sadhakas start rotating like grind mill-stone. This is known as Shaktichalini Mudra and is helpful in the progress of sadhana. Some sadhakas laugh and some cry daring meditative state. This is actually the influence of the vision like union or separation with the Islita being enjoyed during meditation. Some sadhakas start rotating their head during meditative state. It is not because they are under the control of some spirit. On the contrary, this is an emotional state. Feeling heaviness in the head, experiencing the movement as of ants in the head are some other functional activities which the sadhakas experience. Many sadhakas do pass through emotional states wherein either they start dancing or express sentiments through gestures; these have nothing to do with reality.
Perceptual Similar to functional experiences, some sadhakas have perceptual experiences. During meditative state some sadhakas perceive red, yellow, blue, white or smoky colors. These colors are actually connected with energy centers in the body. Many sadhakas have the vision of Gods, Goddesses or Gum These represent the images lying on the subconscious plane and are related to sadhana-upasana of past lives; it indicates the end of past desires and cleaning of the plane. Some sadhakas enjoy pilgrimage. Many sadhakas have the vision of skeleton or the fierce animals like lion, tiger etc. Sadhaka should not get frightened as these visions indicate the transience of this body. Often sadhakas have the vision of snakes. This does not indicate a sin committed in the past but this represents the rise of their Kundalini energy. Sometimes sadhakas may have vision of their dead body or of a near relative; it suggests an augmentation in the life span. Somebody may see a future accident; it means the end of that event by Sadguru's grace.
