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 soul body plus the essence of the soul, Parashakti and Parasiva, together equals the totality of the soul. The essence of the soul is being Siva and the soul body is becoming Siva. The soul body is maturing, growing. We suffer until we learn to control our body, mind and emotions achieving imperturbability even if we find out the world is going to end tomorrow. Calmness is a platform for meditation.
