For a yogi Gita is a superficial book written in a cryptic way
There are many many shloka which have a very profound meaning – but only understood by a yogi. For example krishna says amongst the animals he is the lion etc. The casual reader may take it literally but when the deeper spiritual meaning comes to light the yogi dances with joy
Why did I say it is a superficial book ?. The book only tells what is to be achieved and barely glances at how it can be achieved.
The secrets and the thousands of subtle smaller step to get there are not described. It is quite a fantastic leap of imagination to believe that the vagrant mind will accept God Readily by merely listening to books or people or chanting or mantra
Without going into details , suffice to say a Guru is a must
Finally, even the tithi Janmasthmi , the name krishna or gopal or vasudev are very suggestive of a higher spiritual level. Such things are kept a secret – it is for the good of the public. It gives the true seeker an opportunity to judge and evaluate and make independent decisions about the best road for them
