Yogaswami’s wrote powerful spiritual letters to his devotees.
Here are two to a young man, Yogendra:
Letter to Self who is Yogendra full of Love.
I am with you and you are with me. You are myself and I am you. What is it you fear? Look! I am you. Then what would you do? You must feel and show love. To whom? To everyone. In fact your nature is nothing but love. It is not only yourself, but the whole universe which is overflowing with love.
Yet it is not any other, because you are the only one in existence. You are all things. Study well. Be obedient. Listen to and follow the advice of your father, mother elder sisters, younger brother, as well as your uncle, aunt and elder brothers. Always set an example in obedience.
Siva does all
I am you.
Look: everything is Sivamayam. Then who are you? Who am I? Who is your father? Who are they, and what are all others? Are they not all Sivam? Are you still in doubt? Do you fear? Look! I in you, and you in me, and all being ONE and ONE being all, remain changeless as ever before. Arise, know more and more.
The experience of ananda in savikalpa samadhi has to cease before you can have the deeper nirvikalpa samadhi. Agitations of the mind are released by the attainment of shanti in the anahata and vishuddha chakras. Only man can experience Satchidananda, the all pervasiveness of God. Understanding where we are in consciousness. The realization of one's self as a soul is the first stage of Self Realization, then Satchidanada, then Parasiva.
