There are many techniques and approaches to the subject. One must find a technique that suits you.
When considering Yogic meditation, there are three main types –
Sthula Dhyana – meditation on an outer form employing trataka or gazing upon a material focus such as a flower or sacred object, one that is beautiful or uplifting to awaken spiritual thought and aspiration.
Jyoti Dyana – meditation upon a luminous object that presents a subtler form or focus, such as a candle, lamp or light. Here the time for open gazing is limited , before closing the eyes with the vision turned inward to the Ajna centre between the eyebrows.
Sukshma Dhyana – meditation upon an abstract principle or idea. There are traditional and familiar aids that can be used to lift the mind from the concrete level to the abstract level of consciousness – such as prayer, music, mantra, mandalas, and spiritual symbols.
Meditation achieves a bridging of the planes of consciousness between the ordinary or mundane, material level of thinking and the higher levels of consciousness and spiritual aspiration.
The most successful will be the one which affects and inspires your emotions so that additional energy is available to the intellect by thought and feeling conjoining. Then it is that your Meditation becomes an emotional/mental experience. This is considered as the most complete type of meditation where emotional force or devotion is combined and gives power to the thought force, helping to elevate consciousness to new heights of experience.
Meditation may be practised to help create new ideas (creative meditation)
It may be practised at time of need in prayer (receptive meditation)
It can be used to help focus and steady the mind (reflective meditation )
It may be practised in order to identify oneself with a quality (contemplative meditation)
The final product of any meditation should be a peaceful state of consciousness where difficulties have been dissolved and we have a greater inner strength and sense of attunement to the Oneness or Universal Power and benign purpose behind all life. we feel better after meditating.
