Tattvamasi (तत्त्वमसि)

विभिन्न मित्रों व प्रेमियों को ओशो द्वारा लिखे गए 520 अमृत पत्रों का संकलन।

notes: Tattvamasi is a compilation 520 letters written by Osho in Hindi to his disciples, friends and lovers. Title is a Sanskrit phrase, translating roughly as "That Art Thou". It first appeared in the Chandogya Upanishad and subsequently in many places in Vedantic literature.

The letters of Tattvamasi were apparently published only once in this massive form. The wiki currently has no details about this edition. Previously, they had been published in four other smaller collections:

Kranti Beej (क्रांति बीज) (120)

Path Ke Pradeep (पथ के प्रदीप) (2) (100)

Antarveena (अंतर्वीणा) (150)

Ghoonghat Ke Pat Khol (घूंघट के पट खोल) (150) (that title later changed to Prem Ki Jheel Mein Anugrah Ke Phool (प्रेम की झील में अनुग्रह के फूल))
