This book is a collection of lectures of Mr. Eknath Ranade, a person who worked for social cause and devoted his life to spread message of Saint Vivekananda. The lectures are for students who left their families behind and had come down to serve people through Vivekanand Kendra, Kanyakumari. 

`Sadhana` is meditation. The book has 40 inspirational lectures of Mr. Ranade. It was first published in 1982 and later in 2001.

The book is very good reading for all those who wish to serve people or nation or society for better human life. The email id for having book is vkmadras@vsnl.com. Cost is very low (indian Rs.25/-) while its worth is invaluable. 

I will be writing some of the lectures in `essays` group on EC.
