Varivasya Rahasya Chapter 2
वागिम्द्रियैरागम्ये तात्वातिते महत्तरेsणुतरे I
वयोम्नेsप्युपरि स्थितिमाति विश्वाभिन्ने चिदानन्दे II 108 II
ब्रह्मणि परे नियोज्यः स्वात्मा नदभेदसंप्राप्त्ये I
एष महातत्त्वार्थः ष्रीविद्यायाः शिवेनोक्तः II 109 II
That which is not and cannot be approachable by word, mind or by other senses, that which is transcending the thirty six tatvas and bigger than the biggest and smaller than the smallest with a place loftier than the skies and that which is identical with the universe and assuming the subtle form of Consciousness and bliss is BRAHMAN.
One should concentrate one self with an intention to attain identity with that BRAHMAN. This is the Mahatatvartha of SriVidya expounded by Siva.
Yogini Hrudaya Chapater 2
महातत्त्वार्थं इति यत्तच देवि वदामि ते।
निष्कले प रमे सूक्ष्मे निर्लक्ष्ये भाववर्जिते ॥ ७३॥
व्योमातीते परे तत्त्वे प्रकाशानन्दविग्रहे।
विश्वोत्तिर्णे विश्वमये तत्त्वे स्वात्मनियोजनम् ॥ ७४॥
Paratatva, that is BRAHMAN is Nishkala, that is indivisible. It is bigger than the biggest and smaller than the smallest but cannot be seen. It is the cause of space, the ether. it is non destructible and hence permanent. it is spread all over the universe. It is the light of the light and radiance of the radiance. It is Sat-chit-ananda, the truth, Consciousness and bliss.
One should concentrate one self with an intention to attain identity with that BRAHMAN. This is the Mahatatvartha.
