Tantras : their philosophy and occult secrets

Dhirendra Nath Bose presents an account of Tantra as both a philosophical and ritual tradition, emphasizing its symbolic, metaphysical, and practical dimensions. The book is historically important for introducing Tantra to modern English-language audiences, and readers will find explanations of tantric doctrine, ritual symbolism, and esoteric concepts.

I could not confidently identify a major esoteric or occult author by this exact name. If this refers to a Bengali writer or scholar connected with religious or philosophical literature, I would need additional identifying details to summarize their contribution accurately.
