Jyotish books
for any action there has to be a motive behind it – It can be small- big, personal but there has to be motive as although Vasudev says in Geeta of nishkam karam- To not desire of fruits of your actions and I agree there are few things in life which are beyond profit and loss and you do it for the bigger goals.
I have over 1200 books in which some of them are manuscripts, some hand written and I haven’t came across a book which hasn’t taught me anything as sometimes its not the time that you will get the essence of the book, As if you are mentally prepared the book will start revealing everything you need to know and beyond it and even a single sentence will start giving you cramps due to happiness and same book will seem ordinary for some other person.
