The five Mahāpuruṣa of Orissa are the initiators of the lineages. Our lineage of Vedic astrology comes from the holy feet of Sri Achyutananda.

अच्युताय नमस्तुभ्यं गुरवे परमात्मने।
सर्वतन्त्रस्वतन्त्राय चिद्घनानन्दमूर्तये॥
acyutāya namastubhyaṁ gurave paramātmane |
sarvatantrasvatantrāya cidghanānandamūrtaye ||

Pancha Mahapurusha of Orissa …

Pancha means five and sakha means friends – it is noteworthy that just like Sri Krishna referred to Arjuna as a friend, so also did Chaitanya Mahaprabhu refer to these five Maha Purusha (great men) disciples of his as Pancha Sakha or five friends. Under this page you will find links to their various works related to Jyotish and dharma.
Astrology has a lot to draw from parallels in history. One such parallel is that every time the Guru-Shisya parampara (literally master/teacher & student/disciple relationship in an unbroken chain or lineage/tradition) is to be revived or revitalized, the Guru (Bhagavan as the ultimate teacher) establishes Dharma along with FIVE disciples. This is observed in the panch-pyare (five dear ones) of Sri Guru Gobind Singhji or the Pancha Sakha of Sri Chaitanya Mahaprabhu. These five Mahapurusha disciples were Yashwanta Das, Ananta Das, Achyuta Das, Balram Das & Jagannath Das. Sri Chaitanya has commented that these five are like His five atma-tatwa and are in no way lesser than some of the avatars of Vishnu.

Amshavatar Sri Caitanya Mahaprabhu had five Mahapurusha (great men) disciples in Orissa called his Panca sakha (five friends or witnesses of His activities and teachings). These five Mahapurusha (disciples) were Yashovanta Dasa, Acyuta Dasa, Ananta Dasa, Jagannath Dasa and Balaram Dasa. Sri Caitanya explains that the avatara lila (by Him) is due to the desire of the sakha.

Sri Jagannath Das was the foremost having understood the teachings related to bhakti bhava. Sri Balaram Das understood the tatva. Sri Ananta Das was adept at mantra shastra and understood the complete knowledge associated with yantra. Sri Yashovanta Das had complete knowledge of the rituals, procedures etc, associated with purity. Sri Acyuta Das was blessed to know about the past, present and future events as a part of destiny (Jyotisha).

Sri Caitanya has commented that these five are like His panca atma (five atma-tatva) and deserve the status like that of an avatara. Sri Achyuta was the youngest of the panca sakha. …
