Answer – We all know that the three forms - the Prajapati Brahma, the Mahavishnu and the ParamaShiva, are the three sons of the Aadipita Sahaja Shiva and the Jagadamba.
Also, though the external forms and the mission and purpose of the three are different, their original and the basic form is that of the ‘Parmatma in the form of the Omkara’.
As per the experiences and the deeds of the past births, every person is naturally given likes, dislikes and choices in all matters. Thus, a person may like a particular deity while someone else may like another deity. Also, many forms of the Members of the Chandika Kul are strongly rooted among the masses, and the centralized representative forms of those are always the MahaVishnu-Laxmi and the ParamaShiva-Parvati. Thus, if a person performs the upasana of the MahaVishnu-Laxmi and the ParamaShiva-Parvati, it, in fact, reaches the TriNaath.
The upasana of the bhaktas of the ‘Mahavishnu’ is accepted by the ‘SahajaShiva’ by the name ‘Narayan’, in the infinite-armed form of the Mahavishnu, and also by the ‘Jagadamba’ in the form of ‘Narayani’. On the other hand, the upasana of the bhaktas of the ‘ParamaShiva’ is accepted by the ‘SahajaShiva’ by the name ‘Mahadeva’, in the infinite-armed form of the ‘Shiva’, and also by the ‘Jagadamba’ by the names ‘Shivaa’ and ‘MahaDevi’.
With this arrangement of the TriNaath, also known as the ‘Naathsanvidh’, a bhakta who adores any form is not deprived of the blessings of the TriNaath.
