where can I find the full version of this for free?
I need to chant it and sing it,
this exact way it is sun, in this exact form is the song I know, that I hold dear to me, that holds the key to freedom and liberation,
You don’t NEED to … but you might want to. 
Hmmm, for free? I will share with you that there is no Shakti Prana, no juiciness, in anything that is gotten outside of an balanced exchange. Of course, we are not always being asked to pay money, but you will need to do something to energize your practice of[I] swadhyaya[/I], such as offering your first nine Guru Gitas to something or someone other than yourself. Ask yourself what is the fair exchange and you’ll have your answer.

From Swamiji Muktananda, on pg 10 of [U]The Nectar of Chanting[/U]:
[I]Swadhyaya is a lofty spiritual practice. The truth is that man is an embodiment of sublime love, equanimity and peace. The supreme being dwells within you in His fullness. He witnesses the feeling, faith and love with which you chant, and He listens from within…Sing sweetly and in tune, for the Lord hears every word you utter with great love, and He responds quickly to your feelings. Do not think He is remote. You have become alienated from the all-pervasive being because you have always considered Him to be far away. He is exceedingly close to you—closer than your breath.
