Book for self study

Which book should I refer for self study SFM. On surfing thru net I came accross many authors like CA A N Sridhar, CA S D Bala, CA Rajesh Makkar, Awasth Damodaran, etc. Now I want to buy one which is comprehensive clear and complete book. It may not only serve exam purpose but also in practical real life situations. Like for Income Tax we have an option of Dr.Vinod Singhania which not only serves exam purpose but in practical real life situations also.
