Tatraikagram Manah

The seat is ready from verse 6.11. Now Krishna says: sit down, bring the mind to a single point, rein in the senses, and practise. But practise for what? Atma-vishuddhi — purification of the self.

That word 'atma-vishuddhi' is the key. Yoga here is not about physical fitness or stress relief. It is an inner cleansing. Just as a daily bath cleans the body, daily meditation cleans what is inside — the accumulated dust of restless thoughts, stale worries, and lingering attachments.

One-pointedness does not mean forcing the mind into submission. It means gently gathering scattered attention the way you gather threads to weave a single cord. The senses stop roaming, the thoughts slow down, and what remains is clarity.

Verses 6.11 and 6.12 form a single unit — the first covers preparation of the seat, the second covers what to do once seated. Together they describe the traditional dhyana-asana setup.

Atma-vishuddhi — purification of the self — is considered the primary purpose of meditation in both the Upanishadic and Gita traditions. Only a purified mind can perceive the Supreme Self clearly.
