Meditation is one of India's most ancient meditation techniques. It has been told by lord Krishna, a more than 5000 years ago in Shrimadbhagwat Geeta. The word Meditation means seeing things as they really are. It is the process of self- purification by self-observation. One begins by observing the natural breath to concentrate the mind. In Shrimadbhagwat Geeta, Lord Shri Krishna says,

समं कायशिरोग्रीवं धारयन्नचलं स्थिरः।
सम्प्रेक्ष्य नासिकाग्रं स्वंदिशश्चानवलोकयन्॥१३॥
प्रशान्तात्मा विगतभीर्ब्रह्मचारिव्रते स्थितः।
मनः संयम्य मच्चित्तो युक्त आसीत मत्परः॥१४॥
Samam kāyaśirogrīvaṁ dhārayannacalaṁ sthiraḥ|
Samprekṣya nāsikāgraṁ svaṁ diśaścānavalokayan||13||
Praśāntātmā vigatabhīrbrahmacārivrate sthitaḥ|
Manaḥ saṁyamya maccitto yukta āsīta matparaḥ||14||

"Holding body, head (and) neck erect and immovable (while he remains) firm, looking carefully at the tip of his nose and not looking into the air , with a serene mind , fearless (and) engaged in a vow of brahmachārī --lit. celibate-- , having fully controlled his mind ... such a 'yukta' --i.e. yogī-with his mind fixed on Me, should remain (so) seated and considering Me, the Supreme Self, as the Goal ||13-14||
With a sharpened awareness one proceeds to observe the changing nature of body and mind and experiences the universal truths of impermanence, suffering and egolessness. This truth-realization by direct experience is the process of purification. The entire path (S) is a universal remedy for universal problems and has nothing to do with any organized religion or sectarianism. For this reason, it can be freely practiced by everyone, at any time, in any place, without conflict due to race, community or religion, and will prove equally beneficial to one and all.
