lessons from a good number of teachers conversant in their
respective branches of learning.
As mentioned above that he received lessons in grammar
from his father. Vāmanātha, Bhūtirāja, Bhūtirājatānaya,
Lakṣmaṇagupta, Indurāja, Bhaṭṭa Tota were his teachers in
dualistic Tantras, Brahmavidyā, dualistic-cum-monistic Tantra,
Krama and Trika, Dhvani, Dramaturgy respectively from the
above-mentioned teachers.
He pays obeisance to Bhūtīrāja who was considered by
him as next to lord Śrīkaṇṭha, stating therein that he was the
incarnation of Lord Śiva in this mundane world. It is he who
for the good of all assumed the apara form of a human being.
Similarly in Tantrāloka ( chap. I ), he has expressed deep
respect to Śambhunātha, the disciple of Somānanda and it is
from the former he achieved purity of consciousness. He
considered Śambhunātha associated with his dūtī Bhagavatī,
the partner in the Kula form of rituals, as a person who was
able to bestow release to the world. It is from his grace he
received the Supreme refulgent light of knowledge ( bodha )
by his continuous humble service to him. He frankly admits
that the path of Śāstra, though remained impenetrable before,
has become manifest only due to the grace of Śambhunātha,
the great treasure of all Śāstras. After gaining properly from
his lips the content of the Śāstra which seemed to him
( Rahasya rasa santati sundara ) a wonderful unbroken flow
of nectar with spiritual significance, he received it as a spiri-
tual heritage from Śambhunātha.
He further states that by bathing in the flow of knowledge
originating from Śrīkaṇṭha and following the current of thought
as propounded by Vasugupta-Somānanda-Utpala-Lakṣmaṇa-
gupta on the one hand, and Sumatinātha-Somānanda and
