Ecstacy is only available by spiriutal indulgence. Material nature can't give us everlasting happiness, which our heart is searching for.
Unless one is a completely pure devotee, one cannot enjoy the transcendental bliss derived from chanting and dancing in the ecstasy of the sankirtana movement. Such ecstasy is not possible for an ordinary devotee.
Purport on Srimad Bhagavatam 8.3.20-21
Everyone should be given a chance to take prasada and thus be induced to chant the holy names of Hare Krishna and also dance in ecstasy. By these three processes, although performed without knowledge or education, even even a dog went back to Godhead.
Chaitanya Caritamrta Antya Lila 1.32
Ecstacy means not that I enjoy but that Radha Krishna enjoy.
Anyone who has developed the ecstasy of love for the Supreme Personality of Godhead and who is always merged in transcendental bliss on account of that love, cannot even perceive the material happiness or distress coming from the body or mind.
