परमार्थसार (महामाहेश्वर अभिनवगुप्त - त्रिक-दर्शन, अद्वैत शैव साधना एवं सान्वय सटीक)

Preface
Kashmir Śaivism is a highly perfect school of Indian philosophy,
but has remained more or less confined to the valley of Kashmir.
Scholars in Indian plains and the South developed interest in it as
late as the present century. The subject is now gaining popularity
at some universities in north India as well as in the West. But the
main difficulty in the spread of the study of its important works is
the non-availability of an easy textbook that could pave the path
to explore its finer and sophisticated principles and doctrines
discussed in some very important works like Śivadṛṣṭi, Īśvara-
pratyabhijñā, Tantrāloka etc.
It appears that Abhinavagupta, the final authority on Kashmir
Śaivism, must have felt such lacuna in the academic development
of the subject. Why should he have otherwise taken so much
interest in recasting and re-editing the Vaiṣṇavite Paramārthasāra
of Patañjali for the purpose of expressing through it most of the
main principles of the theistic and monistic absolutism of Kashmir
Śaivism, by the means of an easy and simple method, not over
burdened by terse logical arguments and discussions? That
Paramārthasāra by Abhinavagupta has been serving students of
Kashmir Śaivism as an easy textbook of a comprehensive character
for centuries in the past. Students of Śaivism in Kashmir have all
along been using such work as a textbook at the initial step of
their study in the subject.
Paramārthasāra of Abhinavagupta, being available only in
Sanskrit language, could not at present serve the purpose of
common man interested in the study of Kashmir Śaivism. It
required to be brought out in English and Hindi with explanatory
notes for such purpose. The author of the work in hand prepared
such two editions of the text some years back. But both the
manuscripts remained unpublished for all these years for want of
a publisher prepared to invest a good amount for the purpose.
