पातञ्जल योगसूत्र (स्वामी विवेकानन्द भाष्य एवं सूत्र व्याख्या)

Patanjali Yoga Sutras 3. तद् एवार्थमात्रनिर्भासं स्वरूपशून्यम् इव समाधिः ॥ ३॥ tad evarthamatranirbhasan svaroopashoonyam iva samadhih When that, giving up all forms, reflects only the meaning, it is Samadhi. That is, when in meditation all forms are given up. Suppose I were meditating on a book, and that I have gradually succeeded in concentrating the mind on it, and perceiving only the internal sensations, the meaning, unexpressed in any form, that state of Dhyana is called Samadhi. 4. त्रयम् एकत्र संयमः ॥ ४॥ trayam ekatra sanyamah (These) three (when practised) in regard to one object is Samyama. When a man can direct his mind to any particular object and fix it there, and then keep it there for a long time, separating the object from the internal part, this is Samyama; or Dharana, Dhyana, and Samadhi, one following the other, and making one. The form of the thing has vanished, and only its meaning remains in the mind. 5. तज्जयात् प्रज्ञाऽऽलोकः ॥ ५॥ tajjayat prajnaalokah 99
