Four Means of practice (sadhana chatushtaya), which include Six Virtues (shatsampat), are cultivated on the path of Self-Realization by the school of Vedanta or Jnana Yoga. These allow a clear, steady foundation for the three stages 1. of the practices of listening to the teachings (sravana), 2. reflecting on those teachings (manana), and 3. deep contemplative meditation on those principles (niddhidhyasana). In western phylosophy, it is SQR3= Survey, Queationing, R3: Read, Recite & Resilience.
The sAdhana chatuShTaya is described by Shankara in the vivekachUDAmaNi as follows:
Adau nityAnityavastuvivekaH parigaNyate |
shamAdiShaTkasampattiH mumukShutvamiti sphuTam || - Verse 19.
discrimination of Real from unreal.
Bhagawat Gita explains this in the 3th Chapter Skhetra-Skhetragnya Yoga. This is the first chapter in the third part of Gita i.e. Gnana Kand or Jnana Yoga
detachment or dispassion from sense objects .
It is also called as a state of mind in which there is absence of worldly desires (As said by Sri Ramana Maharshi in Who Am I).
3. shamAdi ShaTka sampatti (a collective group of six behavior traits).
shama means mind-control.
dama means keeping the body and the senses under control.

Unwavering faith in yourself, the sacred scriptures or shAstra, God and Guru.
