Shandilya (IAST: Śāṇḍilya, Sanskrit: शाण्डिल्य) was the Rishi and was the progenitor of the Śāṇḍilya gotra. The name derives from the Sanskrit words Śaṇ (roughly, Full), and Dilam (Moon), thus meaning Full Moon, therefore implying Śhāṇḍilya had great devotion towards the Moon God. His descendants have a matrilineal descent from the Chandravamsha.
Śhāṇḍilya is the son of Devala, the nephew of Surya and the grandson of Kashyapa. He is associated with the Shatapatha Brahmana (X.vi.iii.1) of the Shukla Yajurveda, with the Chandogya Upanishad (III.xiv.1) associated with the Kauthuma shākhā of the Samaveda, and with the Brihadaranyaka Upanishad (X.vi.3) which is the concluding part of the Shatapatha Brahmana. He was also known as "Udara- Śāṇḍilya", and the disciple of Atidhanvān Śaunaka who taught him about the greatness and the limitlessness of Brahman. He is one of the most prominent metaphysical philosophers. He concludes that the essence of the soul is consciousness and that the determinate (the body, the individual, the seeker) finds its ultimate resting place in the indeterminate (Purusha, Brahman) as the indeterminate.
Shandilya's other Acharyas include Kaushika, Gautama Maharishi, Kaishorya Kaapya, Vatsya Vaijavap, and Kushri. Shandilya's disciples include Kaundinya, Agnivesha, Vatsya Vamakakshayan, Vaishthapureya, and Bharadwaj. He composed the Shandilya Upanishad.
Shandilya's devotion towards Lord Chandra is widely known by most but what isn't known by many is that Indumati, granddaughter of Shandilya, married Shatayu, the great grandson of Lord Chandra. The couple moved towards the state of modern-day Odisha. They never ruled like their counterparts and lived ascetic lives, as did their descendants. As Mahapadma Nanda overthrew all the legendary dynasties in India, it was no longer safe for their descendants to claim direct patrilineal descent from Chandravamsha since it would challenge the claim of the former. This line has then merged with Patnaiks in Odisha and then moved down further to Andhra Pradesh. Today their descendants continue to live under Shandilya gotra.
He has been credited with writing the Shandilya Bhakti Sutra. According to the Bhagavata Purana, he was instrumental in resolving certain metaphysical doubts of King Parikshit of Hastinapura and King Vajra of Dwaraka.
Teachings
Śāṇḍilya Vidya is a set of teachings of vidyā or philosophy by the ancient Hindu sage Śāṇḍilya. It is part of the Agnirahasyama of the Shatapatha Upanishad, and its precepts are also set out in the Chandogya Upanishad. The work treats of the universal Absolute (Brahman) and of the practice of faith (Bhakti).
The Śāṇḍilya Vidya
The Śāṇḍilya Vidya is described in the following four passages in the Chandogya Upanishad (III.xiv.1-4) wherein Śāṇḍilya provides the cosmological proof of the Absolute or Brahman, the supreme life-principle, from whom and within which emerge, function, evolve and dissolve all beings and things. Śāṇḍilya states:-
सर्वं खल्विदं ब्रह्म तज्जलानिति शान्त उपासीत । अथ खलु क्रतुमयः पुरुषो यथाक्रतुरस्मिँल्लोके पुरुषो भवति तथेतः प्रेत्य भवति स क्रतुं कुर्वीत ॥ १ ॥
1. " All this is Brahman. From It the universe comes forth, in It the universe merges and in It the universe breathes. Therefore a man should meditate on Brahman with a calm mind. Now, verily, a man consists of will. As he wills in this world, so does he become when he has departed hence. Let him with this knowledge in mind form his will. "
मनोमयः प्राणशरीरो भारूपः सत्यसङ्कल्प आकाशात्मा सर्वकर्मा सर्वकामः सर्वगन्धः सर्वरसः सर्वमिदमभ्यत्तोऽवाक्यनादरः ॥ २ ॥ एष म आत्मान्तर्हृदयेऽणीयान्व्रीहेर्वा यवाद्वा सर्षपाद्वा श्यामाकाद्वा श्यामाकतण्डुलाद्वैष म आत्मान्तर्हृदये ज्यायान्पृथिव्या ज्यायानन्तरिक्षाज्ज्यायान्दिवो ज्यायानेभ्यो लोकेभ्यः ॥ ३ ॥
2-3. " He who consists of the mind, whose body is subtle, whose form is light, whose thoughts are true, whose nature is like the akasa, whose creation in this universe, who cherishes all righteous desires, who contains all pleasant odours, who is endowed with all tastes, who embraces all this, who never speaks and who is without longing— He is my Self within the heart, smaller than a grain of rice, smaller than a grain of barley, smaller than a mustard seed, smaller than a grain of millet; He is my Self within the heart, greater than the earth, greater than the mid—region, greater than heaven, greater than all these worlds. "
सर्वकर्मा सर्वकामः सर्वगन्धः सर्वरसः सर्वमिदमभ्यात्तोऽवाक्यनादर एष म आत्मान्तर्हृदय एतद्ब्रह्मैतमितः प्रेत्याभिसंभवितास्मीति यस्य स्यादद्धा न विचिकित्सास्तीति ह स्माह शाण्डिल्यः शाण्डिल्यः ॥ ४ ॥
