True meditation is the state where you are actively, consciously and continually connected with the one source that gave rise to you and your existence.
Across humanity, this "source" is called by various names: God, Spirit etc. Even scientists and atheists, having applied the most rigorous logic and theoretical constructs, always end at a point, beyond which they have to infer a "source" from which the rest follows. For example, what initiated the Big Bang? Possible answers: something, some source, universal energy, nothing, X.
It doesn't matter what we call it, since we have no direct, unbiased and practical understanding regarding it's shape, form, function etc.
Strictly speaking, meditation is the state in which you are one with this source or we could say, your true self. More popularly, it is the practice of activities which help you to eventually achieve the state of meditation. The state of meditation is unemotional, unbiased and not dependent on any logical or religious model that you may have adopted or developed. It is experiential, but without any emotion, bias or preconceived notions.
The practice of meditation on the other hand is different. In the beginning intellectual models, religion and emotional support can help. But all such mental constructs must be abandoned at some stage or they will hold you back, thus defeating the purpose of meditation. You have to experience the reality for yourself or the proof will not be there (experienced).
Kriya Yoga is a structured form of meditation practice. It is not based on religious beliefs, nor on emotional constructs. It is referred to in many ancient texts by various names and symbols, however its' practice does not require the practitioner to adopt or follow any religion. It's validity lies in having stood the test of time and it's proof is in the individuals' direct, unfettered experience.
