I am not against any wise person who has more knowledge of vedas, shashtra etc but what I felt after watching so many discussion ,there is always hot discussion. Every devotee claim their god to be superior. If you ask vaishnavas (not all are like that) they will claim shivji like he is only devotee of krishna and if you ask shiv bhakt (not all are like that) they will speak same for krishna. And they both have numerous verses to proove their god superior. But I always got hurt by such discussion in which they either insult shivji or lord krishna. when I see so many verses posted by such devotees, i got confused what is write and wrong.why there is so much difference in different verses. some say everybody went to brahma and he told krishna is superior. then in other shashtras brahma says shiva is superior. each shashtra claims their main god as origin of everything and they are written by some sages generation by generation.
There is nothing authentic than that which has been SPOKEN and WRITTEN by god himself and that only ,I am going to present here. It is called as SHIKSHAPATRI which is written by Lord Swaminarayan himself and date is also given by him in his second last verse.
You will find he himself gives instructions which is similar to other vaishnav tradition but what I like the most is VERSE 47 which puts full stop on the difference of Narayan and shiv.
when narayan himself writes this, I don't think anybody is more prudent than Shree Swaminarayan who is himself narayan.
