Yoga means ‘Union’, that is connecting with the Reality, Brahman,the One with no attributes.In Saguna Upasna,worship of Reality with Attributes is practiced.
In fact it was Patanjali who introduced the concept of Ishwara into otherwise worship of Reality as without Attributes or Nirguna Brahman.
When one analyses the systems of Yoga, one would find some common characteristics as well as differences.
While the effort to realize Self is common to all, the methodology differs.
Essentially , there are five aspects or components in Yoga.
1.Postures.
2 .Breath control.
3.Meditation, Dhyana,
4.Nada ,Sound,
5.Tantra.
Patanjali’s Yoga Sutra deals more with Meditation or Dhyana,while the Siddhas emphasize Breath control,Vaasi Yoga.
I shall write more on this later.
And there seems to be some Deities or system of worshiping a specific God or Goddess.
We have, thus, Shaiva,Shakta,Vaishnava Yoga Upanishads.
And we have Samanya, common Yoga Upanishads for Gruhastha or householders and Sannyasa Yoga Upanishads for the Renounced.
I have written on some of these Yoga Upanishads.
Shall write further.
