By Swami Harshananda
The Śāradātilaka, also called the Śāradātilakatantra, is one of the best known and the most widely used works of the tantra-group of Hindu scriptures, which deals primarily with upāsanā or meditation and allied topics on the various deities of the pantheon.
Lakṣmaṇa Deśikendra is the author. He was the son of Śrīkṛṣna and a disciple of Utpalācārya. Out of the several commentaries on it, the Padārthādarśa by Rāghavabhaṭṭa is the most important one.
Rāghavabhaṭṭa was the son of Pṛthvldhara and belonged to Janasthāna. He was a profound scholar and a many-sided genius. He has, in his commentary, drawn the material heavily from the famous Prapañcasāra attributed to Adi Śaṅkara. The work is in 25 paṭalas or chapters and contains 4500 verses in all.
