Samaṣṭi sādhanā This is the kind of niṣkām sādhanā which is done collectively for the spiritual progress of entire humanity.
It is the highest level of sādhanā. The same logic that a teacher must read the book first before teaching the students can be applied to this.
In Kali Yuga, samaṣṭi sādhanā is important as the people do not know the significance of sādhanā.
This kind of sādhanā is more difficult and increases the sātvikta of the entire area.
Samaṣṭi sādhanā is not possible without a guru. Examples of samaṣṭi sādhanā Taking satsangs Helping in organising satsangs, meditation camps, etc.
Telling others about spirituality. Helping others overcome ego by telling them their mistakes from the point of view of spirituality.
Benefits of samaṣṭi sādhanā, Samaṣṭi level sādhanā is more difficult compared to vyaṣṭi but it has added benefits.
We become closer to God Faster Spiritual progress Love for all living beings (prīti) increases Superior level spiritual experiences (anubhutis)
