Several times when we visit a Jyotiṣhī āchārya, they frequently mention the words "Kendra" & "Trikoṇa", while discussing our janma-patrikā Kuṇḍalī.
For instance, the most fear inciting statement one can hear might be -
यजमान, आपके केंद्र में तो शनि, नीच के बैठे हैं। जीवन में बहुत कठिनाइयाँ हैं।
ईश्वर की नित्य उपासना करें ।yajamāna, āpake kendra mein to Śhani, nīcha ke baiṭhe haiṃ. jīvana meṃ bahuta kaṭhināiyām̐ haiṃ.
īśvara kī nitya upāsanā kareṃ.O Dear! the kendra in your chart is occupied by Śhani (Saturn) at its worst. Your life looks filled with hardships.
You must worship the Lord daily.
Further,
आपका त्रिकोण अच्छा है, चिंता की कोई आवश्यकता नही है।
āpakā trikoṇa acchā hai, ciṃtā kī koī āvaśyakatā nahī hai.
Your trikoṇa is well placed, no need to worry.
