Kriyayoga is an ancient Indian science. Rishi Patanjali in Patanjali Yogasastra has clearly mentioned about this Kriyayoga dating back to 15,000 years. All munis, rishis, yogis and Mahapurush as have practised this Kriyayoga sadhana. At a later date Bhagavan Krishna altered the name of this Kriyayoga to Rajayoga. Though Kriyayoga and Rajayoga are two separate names they are essentially the same. Kriyayoga is eternal science. It is the action or process by which one can achieve union with the absolute.
What do we ordinary inexperienced mortals ascribe Kriya to be? Kriya is that yogasadhana which has been conferred by Yogiraj Shamachurn Lahiree Mahasaya to humankind, which we practise after acquiring it through the Guru-lineage. Does stating this include stating all? It is not so Kriya implies karma. Through many previous births, present births and successive many births we perform karmas and karmas of all those births is Kriya. When the body exists then also Prana-karma exists. Birth death cannot occur devoid of Pranakarma, nothing can be created. Therefore in order to comprehend what is the correct Kriya, initially we must endeavour to know – Who am I? From where have I come? To where shall I return? Although all these become cognizant through sadhana an initial knowledge is also necessary. The facet of the sastra – approved initial knowledge is the discussable matter, the rest has to be fathomed through sadhana practice.
Yogiraj has thus expounded –
“Kriya is the actual oblation, everyone should practise this yajna”.
Practice of Kriya infers soul-yajna, the true yajna. The decadence is responsible for making man oblivious towards this yajna, Bhagavan Krishna Shamachurn again reminded this yajna to humanity for them to aquire soul-knowledge. In the past all munis, rishis would practise this. Atmayajna (soul-oblation) is the sastra-stipulated yajna.
Within this period man learnt that barring customs, rites and rules, dharma is nothing. In this chapter of religious decline due to the teaching of the divisibility of the Mahatmas, their followers – the common man has misconstrued all this to be dharma as they have been deeply embedded in the mind of man. Therefore the present day man regarding groupism, sectarianism, customs or rites, pilgrimages, idol-worships, invocations, extolling virtues of Bhagavan etc. as dharma, cannot extricate himself from all these. For this reason everyone is being deprived of obtaining soul-knowledge. But the munis, rishis, yogis of Sanatana Dharma and the sastras have never imparted these teachings. They have only conferred exegesis of Brahma-Knowledge, soul-knowledge and yogasastra.
