Rhythm of the day

Morning, midday, evening

Carry the day with three short pauses: begin with an intention, rest in silence for a moment in the middle, and gently review the day in the evening.

What it isn't
  • Not medical treatment or therapy; it doesn't diagnose and doesn't replace medication or professional care.
  • Not a social network; no followers, no likes, no pressure to share.

Path

The path of knowing yourself

First notice your body, then your mind, then what lies beyond. Five stages; start wherever you like.

    Journeys

    Programmes of several days: one step each day.

    Coming soon

    Erbain: Know Yourself · 40 days

    A shared forty-day path through body, thought, heart, expansion, meaning and service. Everyone starts on the same day, with the same practice each day.

    What the path means

    SendenSana wants to be more than a relaxation app: a companion on the way to knowing yourself. The path moves through five stages, but no one has to walk them in order; the path begins wherever you begin.

    In Sufism this inner journey is called seyr-i sülûk, and its aim is the insān-ı kāmil, the complete human being. The same search lives on under other names in Buddhist, yogic, Christian mystical and Stoic traditions. Here we offer practices from these traditions together with their sources: different paths up the same mountain.

    This is neither a treatment nor an initiation into an order; each practice means only as much as your own experience of it. If a moment becomes difficult, stopping is also part of the path.
