Some Glosary:

Sadhak – Disciple of the path of spirituality.

Sadguru – A qualified, authentic person ordained by God to guide devotees in spiritual evolution.

Sadhana - (Literally meaning harnessing) in parlance of spirituality it means harnessing the inner faculties of mind, which control the sense organs, so that all actions of man (mental, -verbal-physical) are upright. In practice, it requires keeping a constant watch on one's own activities.

What is sadhana:

There are many ways to meditate. They all seem to lead to the same place, so find one that suits you. The benefits are unique for each person, but both physiological and psychological balance is common. Some of the benefits of meditation will be realized quickly, and others over many months, so don't be discouraged.

Throughout your practice, you should bear the following in mind:
Never force yourself into any position or hold it for longer than feels comfortable. Slow and steady effort brings lasting results.

Always breathe in and out through your nostrils and do not exhale through your mouth. This will give you better breath control and conserve prana or energy. Coordinate your breathing with your mantra.

Sit comfortably. A quiet place is preferred, but not required. Close your eyes. Breathe naturally. Sit for about one minute before you begin thinking the mantra to allow your heart and breathing to calm.

Breathe through your nostrils, allowing the breath to flow in rhythm with your lungs. Feel peaceful and at rest. Consciously relax your whole body. When you practice this for a short while, your consciousness will start to flow gently throughout your body. Imagine a sense of well-being throughout, the prana or the vital force, softly coursing through it.

Gently bring your attention to your breath and begin to think the mantra, gently and easily. Just let it come, don't force it. Allow yourself to be absorbed in it. Allow your thoughts and feelings to come and go with detachment. Don't try to control them in any way. Just note them, and when you realize that you are not repeating the mantra, gently return to the mantra. Do not try to force yourself to think the mantra to the exclusion of all other thoughts.

You may experience a deep state of relaxation but it is okay if you don't. When done, take about a minute to slowly return to normal awareness. Be gentle with yourself when opening your eyes or coming to stand after a meditation.

Practice meditation regularly and enjoy the wonders that it can bring to your life.
