A very informative and can probably be a result for a change in our ways of perceiving,thinking,evolving and constant learning.
'Sewa' is the greatest mission of human life to any living form,& It's the way all our karma can be balanced to attain 'shuddhi'.
This book provides a lot of information regarding our karma's. How to perceive a higher state of mind, how the deeds of today will help tomorrow and make way for a change in our lives.
So I say that we should at least repay the help we got from family,friends,gurus,land,nature,any living being by doing Sewa to any living form.
And I conclude my review with a quote "Manava sewey madhava Sewa" --
Sewa to a human is Sewa to god
